Update on my progress. The "setstate up" allows me to read my array now. I seem to have a read error on /dev/da1s1e about 262M from the start of the disk. (i'm using dd if=/dev/da*s1e to copy the contents of each drive to separate files, in case i screw something up and I need to restore a drive and re-try the vinum... don't know if that a dumb idea or not but it seemed logical).
anyway, i have to figure out a way to get around this read error. or find out what file(s) it affects so i can avoid trying to copy them. Any pointers would be welcome (as I fire up google... where would we be without search engines?) >> When i tried to vinum start striped.p0.s1, most of the time >i would get an >> error "Input/output error (5)" but a couple of times the >command hung (as it >> is right now). > >It would be interesting to see the ps -l output for that process and >any other Vinum-related processes. Darn. I wish i had done that for you but I rebooted my server and vinum is running correctly now. When this is all finished, I'll see if I can get vinum stuck again and retrieve anything you wish. thanks for the help folks(greg), the saga continues. -lee >-----Original Message----- >From: [EMAIL PROTECTED] >[mailto:[EMAIL PROTECTED] Behalf Of Greg 'groggy' >Lehey >Sent: Saturday, May 08, 2004 6:40 PM >To: Lee Dilkie >Cc: [EMAIL PROTECTED] >Subject: Re: vinum striped volume has corrupt plex, help needed > > >On Saturday, 8 May 2004 at 13:37:42 -0400, Lee Dilkie wrote: >> Hi there, >> >> I've been running a 5 disk vinum array (sripted, no >redundancy) for a few >> months now.
