[opensuse] Opensuse 11.1 for server ?
Ok, I've read so many 'so-called' complains about opensuse 11.1 for desktop, like burning dvd, problem dialing, and so on.. What I want to know, what about for server usage ? I use some applications like bind, apache, mysql, firewall, etc that already installed in my servers, and some of the use RAID 1 (mirrored), etx3 (i saw that xfs is better now?). I use usb modem cause we have sms application installed. I almost never use X, except for file server that also has printer server, so I can manage print jobs using kprinter or 'printer manager' under gnome. But mostly only has console mode (thanks to yast that can play in console mode). I will install from new, not upgrade. So, is opensuse 11.1 ready for server, or I just have to stick with 10.3 / 11.0 ? regards, -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I have been using oss in a server-role for a number of years (back before it was renamed to oss). Some of my servers are at oss 11.1 now and providing the following services: 1) firewall with multiple public NICs configured in a redundant fashion. 2) File/Print server integrated with Windows AD domains. 3) LAMP + ASP.NET via mono. 4) Email via sendmail/cyrus and various web based email interfaces (twig and horde) 5) Enterprise wide backups via bacula. I have the above working fine on oss 11.1 - at the moment you should be fine provided (strictly from my experience based on issues I am working on): 1) Do not use Reiserfs 2) Do not customize or otherwise install a custom kernel. -- --Moby They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety. -- Benjamin Franklin -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I use all of the above on my servers, except usb modem. Every works well for me, except using a swap partition on raid1. Such a partition will be marked read-only during boot and therefore not used.

It's probably marked 'auto-read-only' - when swap is needed, it will become read-write. /Per -- /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

What about soft RAID 1 (mirror) ? I do need it because in my experience HD failure happens.. RAID 1 and backup every night really helpful.. And what filesystem that recommend for server ? XFS or stick with ext3 ? Thanks for helps guys.. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

xfs and ext3 both are fine. xfs is told to be better for larger files. There is no problem with RAID1, but with other RADI-Levels, because journaling file systems need barrier support and only RADI1 implements that. LVM does not support write barriers, too. if data integrity is important for you, you shall not use LVM or any RAID except RAID1.

RAID1 works fine (Although, yast installer did screw up the grub/menu.lst so the machine wouldn't boot. See: https://bugzilla.novell.com/show_bug.cgi?id=445602) I have used 'software md' raid and 'bios dm' raid without any issues since 10.2. Currently I have 6 servers (10.3-11.0) running raid1 arrays without a single issue. -- David C. Rankin, J.D.,P.E.

I joined the mdraid mailing list a couple months ago. I mostly lurk. Most of the problems I see people have is when they try to grow / reshape a raid array, or when they have serious problems and try to fix it. Surprising how many people post about experiencing a dual disk failure and need to try to rebuild without restoring backups. Apparently mdraid is a little aggressive about kicking drives out of the array, because often they are able to get the array operational again with exactly the same hardware. I'm still a hardware raid guy, and having monitored the mdraid list for a couple months, I'm likely to stay one until mdraid becomes more tolerant of transient issues. To be fair, hardware raid may be just as problematic in situations where power supplies, cables, external enclosures are behaving erratically. I just have not watched their support channels so closely.

I don't beat up on my drives or anything like that, but my experience with the software raid has truly been that I set them up, check them once, and then forget about them. I have had some spinning for 2 years now without a hiccup. (knock on wood). I am fairly cautious though. When I set one up, I used matched pairs of drives (nothing special, just 2 of the same type ordered at the same time) check that all is good with mdadm or dmraid or just watch the bios output if it is a bios raid, and that is all the thought my arrays ever get. The only death nail I see, which would hold true for hardware of software raid, is memory corruption that spews gibberish all over you drives. Raid or not, if that happens, you better have a backup handy... -- David C. Rankin, J.D.,P.E.

From what I've read I think all of the vendors are putting out the occasional bad model right now as they are pushing the limits on capacity / speed. And since a given model is not in production all
David, In the last year I have / heard of a lot of bad "hard drive batches". In particular we bought a batch of Seagates and several of them failed in the first 50 hours of use. In one case I had 2 copies of the same important data. Both drives holding it failed within 8 clock hours of each other and I was left without a copy. Fortunately I swapped the drive electronics of one of the failed drives with another working drive and was able to copy the data off. Thus, per the mdraid list the current recommendation is actually to use drives from different batches and even from different vendors. The idea being you reduce the likelihood of a double failure and in turn data loss. A lot of people are also moving to Raid 6 because the reliability of drives seems to have gone down so significantly in the last 12 months. Mostly it is tied to specific models, so you can get the impression that all is well if you are not surveying a large number of models. that long it is hard to know the quality of what you are about to buy. Also, Sata is far more demanding of power supplies than IDE drives were. So lot of people are building servers with 4 or 8 drives in them and having mdraid kick out multiple drives due to a single mis-behaving component (the PSU). This was a bigger issue a couple years ago than it is now. I don't know if users have gotten smarter, or if the PSU manufacturers are doing a better job, or maybe the sata drive makers have made the drives more tolerant of power fluctuations.
