SCSI RAID recovery
by Robert Amodeo 19 Jan '06

19 Jan '06

I have a fileserver running SuSE 8.0 with 2 IDE Drives and a SCSI RAID (RAID5). The system boots up to one of the IDE drives, and the SCSI RAID drive runs as a mounted filesystem (/dev/md0). (all filesystems are REISERFS). Problem: The SCSI RAID drive has crashed (won't boot up), and I need to recover it (repair it, through some utility). Further: The software does not seem to want to mount the disks, even though the SCSI BIOS (Adaptec) recognizes the disks, and they are listed as OPTIMAL. I tried to repair the disk(s) (with reiserfsck), but it produced an error message: reiserfs_open: bread failed reading block 2 reiserfs_open: bread failed reading block 16 reiserfs_open: neither new nor old reiserfs form found on /dev/md0 The literature suggested that this error message is hardware related (either a disk is physically damaged, or maybe the RAID isn't recognized), but again, the disks are recognized (and therefore, so is the SCSI Card). I tried to boot up with SuSE CD 1 in Recovery mode, but not sure what to do there (i.e., after the root prompt - just run reiserfsck?). Literature suggests there are plenty of tools to handle disk recovery, and especially RAID support, I can't find reference to them anywhere. The installation of the RAID was trivial (using the YAST2 partitioning GUI window on startup), and yet recovery seems to be a mystery. This can't be right. Does anyone know where there are "decent" and "usable" recovery tools? OR ... does anyone know what "specifically" to do in this case? Can I re-partition without formatting, and recover the existing data? Any help is appreciated - I'm sure I'm missing something "obvious", but can't find "obviously" what to do in the literature, docs, etc. Thank you.

stable,updated,zero-cost,FLOSS virus software
by David Storrs 17 Oct '05

17 Oct '05

What are people using for anti-virus software? I've got BitDefender running on my machine, but I'd like to find something zero-cost that has a nice GUI so that when I set up boxes for friends and family, they can use it. Regularly (and automatically) updated virus definitions are a must, here. Dave

Internet connection through modem in 9.1 is slow
by Carlos E. R. 09 May '05

09 May '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Since I updated, a month ago, from SuSE 8.2 to SuSE 9.1 I had the feeling that the modem connection was slower than previously. Previously I saw comments on this list to that effect, but they seemed to be related to winmodems. It could be just an unjustified feeling, therefore I started to pay more attention, and finally I ran some test to confirm it. Thus, I can now confirm it: there is something in SuSE 9.1 that makes Internet connection using a modem definitely slower than previous versions of SuSE. ** System ** SuSE 9.1 on a P-IV at 1.8 Ghz, with 700Mb ram. Internet connection through external serial modem (3COM US Robotics, V90 type) - no winmodem involved. I have tried reducing the TCP window to 8Kb, as recommended on the SDB: no noticeably change. Patches (YOU) are almost up to date - at 2K/s a kernel update is... fearsome :-( Connection is started using wvdial on an xterm (same definitions as in SuSE 8.2 previously). Desktop is gnome. Running susefirewall2 and DNS locally. More info: just ask for it :-) ** Symptoms ** Mail fetching (fetchmail) runs jerkily, it runs and stops, seldom reaching 5Kb/s. It may stop for as long as 1 minute, timing out. But connectivity is not lost: pings to the same server from which I'm downloading works; one provider yields 20% packet loss, another 1% - so packet loss is probably not the main issue. YOU takes seemingly for ever. Ftp downloads are slow. Browsing of large pages is also slow. ** Tests done ** 1) Plug the modem on my old Pentium 120 machine, running SuSE 7.3, text only. Route through intranet (one ethernet cable, direct, 100 Mb/s). Change default route in main computer (SuSE 9.1) to eth0, and do the downloading, name solving, etc, on this "fast" machine - no software is changed at all - except that wvdial and pppd runs on the other 7.3 machine. +----------+ +-----------+ +------+ | P-120 | | P-IV 1.8Gh| ---phone---|modem |---rs232---| SuSE 7.3 |--eth--| SuSE 9.1 | line +------+ | | | (fetch) | +----------+ +-----------+ Run and time a single download of 738442 bytes. During this download no other Internet activity is running (no fetchmail, no browsing, no email sending). There is the local firewall (Susefirewall2) and a local dns server. No high load tasks are running (no updatedb, for example), only the xterms on which I see the logs and enter the commands. 2), 3) Plug the modem back on my P-IV machine running SuSE 9.1. Remove default route to eth0. Repeat the download, using two different providers, to make sure. Everything else is the same. ** Conclusion of the 3 tests, in brief ** When routed through the old computer running SuSE 7.3, throughput is 5.04 KB/s (on previous, non meticulous tests, I saw speed peeks up to 8Kb when downloading email - surely due to compression). When using the fast, Pentium IV machine, with SuSE 9.1, average speed is between 1 - 2 Kbytes per second! (even less, in fact). This is a disgrace :-// I see a lot of ppp "decompression error" in the kernel logs: Jul 23 21:22:39 nimrodel kernel: PPP: VJ decompression error I count 37 of them during test #2 (none during test #3) - compared with 560 during 4 months usage of SuSE 8.2 on this same machine. ** Wild non-educated guess ** The kernel is loosing ACK packets, so the servers waits. ** Detailed results ** *********** TEST #1: teleline - routed through P120, SuSE 7.3 ************** cer@nimrodel:~> date ; time wget --timeout=45 --waitretry=10 --continue "http://old.spamassassin.org/released/Mail-SpamAssassin-2.63.tar.bz2" Fri Jul 23 20:52:39 CEST 2004 - --20:52:39-- http://old.spamassassin.org/released/Mail-SpamAssassin-2.63.tar.bz2 => `Mail-SpamAssassin-2.63.tar.bz2' Resolving old.spamassassin.org... 64.142.3.173 Connecting to old.spamassassin.org[64.142.3.173]:80... connected.

It is a very proper question :-) Well, it depends. There are two ways. If your computer is up all the time, and has a permanent network connection, you can use the ntpd daemon, which polls a set of servers about once a minute, and _very_ slowly adjusts the system clock; it can even note the systematic error or drift, and take that in to account to discipline the system clock. There are many options available for the daemon: see full doc in: http://localhost/usr/share/doc/packages/xntp-doc/html/index.htm Or, you may have a temporary network connection, like I do; I will explain this in some detail. We can adjust the clock to "internet" time, once, sometime after we connect to internet. This, apparently, can be done with the daemon, using some option I don't fully understand. Or we can use ntpdate - a program which is to disappear some time in the future, but that I use, and SuSE uses as well in its own script. For this, we can simply call "/etc/init.d/xntpd ntptimeset" - and assume that when "ntpdate" finally disappears SuSE will adjust the script appropriately ;-) Of course, /etc/ntp.conf has to be configured; at least, it must have a list of servers: server IP_address server name_address This is sufficient for "xntpd ntptimeset" to work; just leave the rest of the config at the default values. If you want to use the daemon, then I'm not the person to ask :-) Ok, so when is the appropriate time to make this time adjust? Well, ideally, during system boot-up, after network connection is established. This is done properly by the service xntpd, if enabled. The SuSE script "/etc/init.d/xntpd start" does first a clock set using ntpdate, if the variable XNTPD_INITIAL_NTPDATE is set to "AUTO". Then, it starts the daemon to keep time synchronized. And, if our network connection is not permanent? Then, the script "/etc/ppp/poll.tcpip", which is called from "/etc/ppp/ip-up", will adjust the clock first thing: assuming we have some servers configured, it will be done every time we connect to internet with the modem. I do it differently, only once every five times, and I also update the hwclock. The danger of this method is that the clock might suddenly go forward or backward a bit (seconds or hours, it depends): not very nice on a *nix system, but we can not avoid it. More details to be aware of: what happens to the hardware or CMOS clock? Well, the script "/etc/init.d/boot.clock" (read it, it is documented) does this sequence of things (using the command "hwclock") before starting system services: - Create if it doesn't exist, the file "/etc/adjtime" - Adjust hardware clock (CMOS) for known drift during the time the computer has been off; this depends on the previous file to work. - Copy CMOS clock (hardware) to system time (CPU and OS maintained). After this, the system goes fully up, and maybe, the clock is adjusted from the internet or by hand (danger!). But (and this is very different than windows) the CPU maintained clock has to be copied back to the CMOS, because the kernel doesn't do it. SuSE does it in the script "/etc/init.d/halt" that copies system time to hardware time just before power off. Me, I prefer to do it just after I adjust to network time, inside "ip-up.local", like this: /usr/sbin/rcxntpd ntptimeset /sbin/hwclock --systohc More things to be aware of: a common mistake is manually adjusting the system clock from kde control center (for example), and not updating the hwclock at the same time: the drift adjust algorithm of hwclock thinks that the CMOS clock is fast or slow by the same amount you adjusted the clock, and the next boot it will adjust the time by several hours... The solution is to delete "/etc/adjtime" and call "/sbin/hwclock --systohc" just then (documented on the SuSE sdb). Well, this has been enough chatter on my part; let's hope I didn't make many mistakes :-) -- Saludos Carlos Robinson

Kylix 3 in SuSE 9.0
by Damon Register 10 Jan '05

10 Jan '05

Finally I got Kylix 3 installed on SuSE 9 but found trouble right away. Even a new blank project fails to compile. I get a bunch of errors with a file called time.h. After a little searching in this group and elsewhere on the net, I found several references to http://unvclx.sourceforge.net so I got 3.5.1 and installed but still I have the same problem. I have seem some posts here from those who say they have been using Kylix but I would certainly like to know how they got it to work. Yes, I know at least one post said there wasn't much future for Kylix and after my experience so far, I am inclined to agree. I would love to use something like Qt but I don't know of any gui builders for the windows side. I have heard of tools for Linux but since I am wanting to write for both platforms, it would be nice is there was a tool for both sides Damon Register

Why am I paying SuSE for a distro if the software developers bundle the software?
by me＠prestoncrawford.com 21 Nov '04

21 Nov '04

I asked SuSE support about the lack of Gnome Conduits and this is what I got... "Unfortunatly it is up to the developer of the software to package it up for each distribution they wish to support, unfortunatly, if the package is not available for SuSE linux all I could suggest would be searching for the sources and compiling it on your system, beyond that theres not much we could do." So... (SuSE team listening) does this mean that every single RPM installed in SuSE is provided by the people who developed the software? The Kernel, Gnome, KDE, all of that comes to SuSE already ready to go. SuSE doesn't do anything, really. What, then, does SuSE do? Burn them all onto a CD for me? Seriously, this is the most ridiculous response I've ever received from a SuSE rep. I don't, for a minute, believe that the developers of Gnome-pilot-conduits created RPMs, packages, etc. for Mandrake, Fedora, Ark Linux, FreeBSD, Debian, etc. but not for SuSE. That's absurd. All I wanted was a straight answer and I got the biggest line of bull ever. Preston

Failed to read wlan0 statistics: error=-61
by Matt Burke 23 Sep '04

23 Sep '04

I'm running SUSE 9 pro on a Toshiba Satellite 1115-S123, my wireless card is a Microsoft Broadband Networking MN-520 (prism chipset), and my access point is a D-Link DI-514. In Gnome, I have the wireless applet in the toolbar to show my current signal strength. From time to time, the applet will show N/A and when I check /var/log/messages I get this (ignore the old dates): May 31 13:00:55 slacker kernel: prism2sta_mlmerequest: Failed to read wlan0 statistics: error=-61 May 31 13:00:57 slacker kernel: prism2sta_mlmerequest: Failed to read wlan0 statistics: error=-61 May 31 13:00:58 slacker kernel: NETDEV WATCHDOG: wlan0: transmit timed out May 31 13:00:58 slacker kernel: hfa384x_tx_timeout: Implement me.

I cannot get wlan0 back up using rc network restart - I have to go in to YaST, change the settings then change them back to what they were, and apply the settings. As far as I knew YaST was basically doing the rc network restart as I was not changing any settings. If YaST cannot bring wlan0 back up I have to restart. On every boot I must also manually bring wlan0 up and add a route. I made a script for this but it's a real pain in the butt. I guess my questions are: 1) Does anyone have an idea what is going on with wlan0 and why the card cannot read the signal? 2) Is there anyway I can get my wlan0 IP and route to stay even after reboot? Any info or help would be great, thanks in advance =] Matt (By the way, I did get great joy from contacting Microsoft's Broadband Networking support and thanking them for using the Prism chipset in there cards - helping me get wireless working in Linux)
