In a galaxy long ago one could boot into openSUSE by putting level 1 in the boot command and login as root after which you could manually check for any errors in the ext3 or ext4 file system by issuing the following commands: mount -o remount, ro /dev/<hdX>/<sdX> followed by e2fsck /dev/<hdX>/<sdX> and, if errors were found, follow the prompt(s) to have any errors repaired. A few minutes ago I tried this on the laptop which has Tumbleweed installed on ext4 file system (I didn't want to this experiment on my main system on the desktop). Booting into level 1 seems to be OK and logging in as root was OK but then when I issued the command- mount -o remount, ro /dev/sda5 [#] I got the response (error msg) that- mount: / is busy The above sequence of commands worked for years in SuSE and then openSUSE so why has it now stopped working? Or put another way, how does one go about manually checking the file system for errors by running "e2fsck"? Why run "e2fsck" manually you may ask? Because I have found that the checking which is done automatically after X number of boots by the built-in system does not always pickup the errors in the ext3/4 file system. (Don't try to convince me otherwise because I have proven that to myself several times over the years. In any case, this is not the point. The point is why I now cannot check the file system using the method above which was spelt out in detail in the Administrative Manual which came with the version of S.u.S.E.?)

not a real answer, but you can still boot a rescue or live cd (if nothing else works) think also to try bdablocks -s /dev/sd... just in case some bad sectors shows jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

what does fstab have to do with the problem? fskhave to be used on non mounted system, use better fdisk -l ti know what the partition are I have two (old) disks with bad sectors on my desk, tested last week... fsck is for file system problems, badblocks for hard disk problem. and by the way usb booting is faster than dvd :-) I know it's slow, using ssd on my main, most anything else seems desperately slow :-)) jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

My "rescue disks" are very fast booting and very easy to find, yet another advantage of multiboot HDs. Install first "upgrade" of the first installation as a new installation on a separate / partition, and you don't have to restore from backup, try installing again, or reinstall the old, after finding the "upgrade" fell short of expectations, yet once the new turns out to be an acceptable replacement, the old sits in reserve not hurting anything, and taking up relatively little space on modern giant HDs, waiting for an opportunity to rescue the new. I have one system ready to boot at any time openSUSE 10.0, every openSUSE since released, plus Tumbleweed. Not to say it's right that what used to be possible no longer is, but that seems to be the legacy of started from scratch replacements for things that worked (KDE4 then KDF5 replacing KDE3; systemd replacing sysvinit; dracut replacing mkinitrd; wayland to be replacing xorg; etc.) that FOSS evolution has become. The wisdom of experience is routinely discarded, providing vast opportunities for new bugs and more downtime on account of the "upgrading" necessary to remain reasonably secure in an Internet-accessible environment. -- "The wise are known for their understanding, and pleasant words are persuasive."

Hi, I have not tried your experience so far on my standard 13.2 nor Tumbleweed which I have not available here but if it really doesn't work you can also try to verify your disc by booting your system with gparted: http://gparted.org/livecd.php which contains a check file-system option.

Hi, I have not tried your experience so far on my standard 13.2 nor Tumbleweed which I have not available here but if it really doesn't work you can also try to verify your disc by booting your system with gparted: http://gparted.org/livecd.php which contains a check file-system option.

The SystemRescueCD (http://www.sysresccd.org/) also contains GParted which will check file systems (Including, BTW btrfs - with a qualification!). However, the check in GParted will do a check *AND* repair which is NOT what I really want. I don't know if GParted uses 'e2fsck -p' in this check process but I have a note in my "little black book" which states that this command has a problem and that it causes problems/corruptions and so not to use it but rather simply follow the prompts which e2fsck gives you if it comes up with errors in the file system to repair any damage. So, from my point of view the GParted path is not what I want. In any case, using either the GParted CD you mention or GParted in the SystemRescueCD is having to use a third-party application to do something which was - and should be - available in openSUSE itself. As I state in my initial post following the commands I quote when and after booting into S.u.S.E./openSUSE checked the file system so why should this still be the case? Or are we now moving towards the MS model where everything is done by 3rd party software?

Considering that '/' is where all the "really good" stuff is, checking '/' for errors is rather "front-page stuff" wouldn't you agree? :-) It was _very_ simple in the past (as I describe in my initial post) therefore it should just as simple to do so now. Agree?

As I mention in my reply to jdd, GParted can check btrfs for errors with one exception which has to do with UUID. I don't know what that means but you could check it out (as I wouldn't touch btrfs with a forty-foot pole while its still in its alpha stage).

NOT! The core stuff may be in /bin and /lib but the "fun" stuff is in /opt and /usr/local. Heck, many of the essentials are in /usr/bin and /usr lib.

I know that you keep trying, but you often miss the point :-) (and I mean this in a nice way). When one installs openSUSE, the installation process gives you the option of creating '/' and '/home' directories (the swap partition is not really mentioned in the choice as I remember). This means that all the "good stuff" is sitting in '/' when oS is installed. Yes or No to the above last paragraph? And as a normal, standard, sane, user of openSUSE I do not go about bothering about all the /bin and the /lib and the /usr/local and the /usr/bin and the /usr/lib s*** you mention above. I simply want to use openSUSE - just like someone who is into Windows wants to use Windows without having to take a Microsoft Certified Training Course to fiddle the Window's guts. Got the picture? :-) Alright, there *are* a few things I can fiddle with in oS to suit myself but they DO NOT involve all the "/opt" etc and so on which you mention :-) . I install openSUSE on a partition which is '/' and with a swap partition. NO separate /home - just '/' and swap. That's it - except that I create on a second HDD a partition to where I then SYMLINK most of the directories in my /home partition.

...

The logic behind having one FS for the whole system, the plan behind BtrFS, spanning multiple spindles, scares me.

BTRFS terrifies me as well which is why I won't touch it for years until it proves to be as reliable as, say, Reiserfs, or ext4 (with whatever faults it may have).

I said NO and I meant NO. NO means NO. To coin a phrase :-) When one installs openSUSE the installation process gives you the option of creating .... *any number of partitions*

And as a normal, standard, sane, user of openSUSE I do not go about bothering about all the /bin and the /lib and the /usr/local and the /usr/bin and the /usr/lib s*** you mention above.

As a normal, standard, sane use of openSUSE ... who is a careful and diligent computer user who make sure he backs up his work, I partition my system for robustness, ease of backup and ease of restore. This involves partitioning along functional lines. Once upon a time UNIX didn't have /home. Its introduction was a goo innovation! Everything to do with my web server is on /srv. That is a functional division. OK, so if you don't have a a web server you won't care Local packages, Xmind, freemind, scrivener and the like end up in /opt I want to keep those, maybe move them when I get new h/w and don't want them zapped when / gets reformatted in a new installation. That justifies a functional division. OK, so if you never install custom stiff you won't care There are quite a number of reasons, many of them security (and not just hack-related but also dealing with containment) related that justify having a separate /tmp. You may have enough memory to make this a tmpfs :-) I exclude /tmp from my backups very simply by having it as a separate partition. Or you may not care. Even under /home I have mounted partitions. - My Documents - My Music - My Photographs It makes space management and backups easier to manage. Part of my backup strategy is to have (data) partitions that are under 5G so they can fit on a DVD. Regular readers will recall that I use LVM so more partitions - aka logical volumes - are easy for me, as are taking snapshots and making backups from the snapshots while 'live work' continues. This has all to do with planning and a strategic attitude towards disk management. Very little of *MY* good stuff lives on the ROOT file system. So when I said NO I meant NO. Of course you may about care about such matters as backups and restore, about making disk management easier. You may not care. I came to all this though unpleasant occurrences, inadequate backups, failed media and more. Call it paranoid: I now expect things to go wrong so I adopt a strategy to try and minimise the impact and make it more manageable. When one installs openSUSE the installation process gives you the option of creating .... *any number of partitions* I take that option. I take that option based on experience and prudence. Because I CARE ABOUT MY DATA. As far as I am concerned, the "Good Stuff" is the stuff I have created or purchased. So NO, I don't think the good stuff should be on the root partition when installing. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

See my comments in this thread about using the GParted (in the Rescue Discs).

And why do you want to use gparted, and not e2fsck? - -- Cheers / Saludos, Carlos E. R.

The above sequence of commands worked for years in SuSE and then openSUSE so why has it now stopped working?

systemd, what else?

Since long time ago I don't use this approach, it failed for one or another reason. Instead, I keep some type of rescue system and I do the fsck of the target root from there. It can be the installation DVD, or another partition on the same hard disk with at least a minimal install. Recently, it can be the XFCE CD rescue image which you get from our download page and place on a USB stick. Yes, it is of course slower than the real system, but you get an openSUSE graphical system running.

It probably means that some files are open for writing. Maybe you can find which with lsof. - -- Cheers / Saludos, Carlos E. R.

dracut usually performs fsck anyway; if in doubt, today one can simply use rd.break=pre-mount to stop in dracut shell before real root is mounted, then do fsck (fsck for root should be present in initrd) and Ctrl-D to continue. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

interesting. going to advanced menu, "e" to edit and add rd.break=pre-mount on the kernel line, gives you the emergency shell where one can use fsck. that said, no fdisk _l, one have to remember the partition number jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I am not about to go trying out your suggestion as I simply do not have the time but please refer to my earlier post where I stated that the RESCUE DISC - at least for 13.2 - contained GParted which does a CHECK AND *REPAIR* run on the partition you want checked. I also stated that if this Check and Repair feature in GParted used the command 'e2fsck -p' then I do NOT want any part of it because an entry in my "little black book" states that this '-p' option has problems and can corrupt the file system - and therefore I have never used it. So, any 'rescue' disc is a no-no unless it uses some other command to do e2fsck or if the '-p' option in this 'e2fsck' command has been fixed. Since I have not received any comment re what "check and repair" in GParted really does and/or if the "-p" option in e2fsck has now been rectified, I am not using any 'rescue disc' which has GParted.

Thanks for this, I will use 'lsof' to check this. However, as I already stated, in the past the commands I mentioned in my OP did the job perfectly. The same commands should also work as well NOW - otherwise it is a regression in openSUSE (nee S.u.S.E.).

You must be confused. The openSUSE rescue disks does _nothing_ automatically. It is up to you to start gparted, or a terminal and run fsck with whatever options you want. - -- Cheers / Saludos, Carlos E. R.
