Re: Booting Problem After Power Loss (fsck)?
Good news and bad news: Good News: System seems to have recovered. Booting into single user mode and running fsck worked great for / and /var, but did nothing for my /usr partition with all my data. After letting fsck run on my /usr partition for 4 days, the raid controller appeared to stall and the machine did not return to a prompt. Regular boot (multi-user mode) somehow worked where it would not work before, and background fsck on the /usr partition eventually ended. The system is now up and reachable, which is all I care about. Bad News: No one who read my last message offered to help. I suppose you can draw your own conclusions about the community-like nature of FreeBSD use in the Bay Area (home to UC Berkeley, FreeBSD Mall, and birthplace of the FreeBSD movement.) -- Rishi Chopra http://www.ocf.berkeley.edu/~rchopra Rishi Chopra wrote: I do not have the FIX-IT CD or another FreeBSD machine.

I could really use some help getting the filesytem up again; my heart can't take another failure like this, and I'm ready to give up computers (recreationally and professionally) if I can't get this problem fixed. I had just finished recovering from a 2 year reconsolidation of life and data (a 75GXP/Raid-0 failure and data loss occurred while I was studying at UC Berkeley and triggered a very nasty chain of events culminating in this problem.) I can't handle going through another data consolidation; recovering from a recent thyroid removal and a 12-hour neck dissection/removal is a full-time affair, and the 30 some-odd staples in my neck greatly limit my ability to sit at the computer. Looks like the important thing is for me to make a new friend in the FreeBSD community and a new start on computing, or bid y'all adieu. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

If you have the kernel with options DDB options BREAK_TO_DEBUGGER and no disk activity I suggest that you break to debugger hitting Ctrl+Esc and try to gather some info from there. Note that in case fsck is actually running this could further damage you fs, but since you can't do anything else I would say to give it a try. To summarize: 1. See if you have disk activity when fsck seems to be stuck. 2. Try fsck (-p) first on root, the on tmp, /var, /usr, /home. 3. Esp. if fsck / doesn't go ok try booting verbose with Fixit CD and run fsck from there. 4. If 1 gets you the same results try putting the disk in another machine where you have debugging options in the kernel, break to debugger and gather info from there (esp. if you're running 5.x try asking on current@ what exactly to look for in the debugger). -- IOnut Unregistered ;) FreeBSD user ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

It should have outputted something else between Phase 1 and FILE SYSTEM STILL DIRTY. Will fsck continue attempting to fix the filesystem? Have I suffered a total loss or is fsck still doing its thing?
