Re: Reiser FS will not boot after crash
Hi, Sorry to take so long giving you a response. I did connect to the box as it crashed [via ssh]. There were no terminal messages [tail -f /var/log/messages]. This latest time an initial window for camorama was starting to open. You ask, "Am I willing to help?" debug the problem. Absolutely. [Linux has given so much to me!!] I reloaded camorama, so I should be able to reproduce the problem. The problem (not being able to boot) occurs frequently though not every time I run camorama. So my simple solution has been just to not run that program. This box has LILO on the master boot block. This chains to the Knoppix partition which has GRUB as the partition boot loader. As mentioned GRUB starts but then claims it finds an inconsistent filesystem. This repeats over and over until fsck.reiser is run on this partition from a different OS on a different partition. fsck.reiser replays the journal at first and then examines the filesystem and finds nothing wrong. I assume I am using the "stock" GRUB which Knoppix 5.0.1 installed since I haven't knowingly changed it? Perhaps the "problem" is simply that Knoppix installed an older version of GRUB ? john On Tue, 5 Sep 2006, Vladimir V.

Mt Knox Datacenter in Franklin TN
Can you please help me to contact your Information Technology Director? My company has just opened a new computer datacenter in Franklin, TN for the purpose of providing disaster recovery, business continuity, and outsourcing services to small and medium size businesses in the Nashville area. This facility can also aid companies such as yours in compliance with HIPAA and Sarbanes/Oxley. If you can provide me with contact information for your IT director, it would be greatly appreciated.

Transferring / to a reiser3 partition removes this problem. Shutdown and startup proceed normally. I am using util-linux-2.12r with gentoo patches -r4. This was updated on 9/4/06. I am thinking I will downgrade to -r3 and see if that removes the problem. -- Peter + Do not reply to this email, it is a spam trap and not monitored.

On initial startup, the error occurs. Then, after CTRL-D, the system reboots and all is fine. Then, after the day, normal shutdown, then abnormal startup. Some more information, I looked at the output from the final mount -v -n -o remont,ro / command, it appears perfectly normal. However, I am not sure it is working normally! -- Peter + Do not reply to this email, it is a spam trap and not monitored.

My version of baselayout has that fix, but that does not appear to be the problem. I think it has more specifically to do with the way the remount option is affecting the reiser4 fs. And, only / is left when the remount,ro part comes anyway. Everything else is unmounted by that time. -- Peter + Do not reply to this email, it is a spam trap and not monitored.

There was a bug in baselayout which caused partition (except /) not to remount ro properly. The bug number is 131001 [1], is this your problem?

It is my BELIEF that the error is caused by an improper shutdown, not an improper startup. This is because after the error, typing CTRL-D to continue merely unmounts the / volume and reboots again. Next time the system runs fine. If it was a startup problem, wouldn't it occur every time then? If you recall, when I wrote about this with teh Sabayon Linux CD issue, it was not unmounting volumes or syncing them properly which led to a similar problem on startup. That's why I thought the mount -o remount,ro / command was the culprit. I think the only way to nail this down will be to create a separate partition, identical in all ways, except with reiserfs or ext3 instead. See what happens then. -- Peter + Do not reply to this email, it is a spam trap and not monitored. I can be reached via this list, or via jabber: pete4abw at jabber.org ICQ: 73676357

In the first mail you said: "On reboot or after a poweroff, root does not mount properly, and after some modules are loaded, there are segfaults when running init scripts." This looks like you have problems on startup.
