I accidentally moved a backed-up volume from partition a to b. I moved it back, but now the backup volume is misbehaving. (The process is REPEATABLE!)
I can't seem to remove all traces of it, but neither can I use it. I can get root access on the (Linux) file server and start hacking files directly, but perhaps someone on this list can help me avoid making a terrible blunder. Here's a partial history. Notice that after the "zap", vos backup gives a different error once, but then it's back to the same set of errors again. I've been able to create backups of other volumes on the same partition today. So it seems that vos zap doesn't actually zap everything. Something's hanging around which is preventing vos backup from working. (And no, salvaging doesn't help either.) Any advice? John P.S. If you cc me in a response, I will get it quicker. ------------------------------------------------------------------ admin 79 % rxdebug localhost -port 7001 -version Trying 127.0.0.1 (port 7001): AFS version: OpenAFS 1.4.11 built 2009-07-13 admin 80 % rxdebug jeremiah -port 7000 -version Trying 129.89.143.70 (port 7000): AFS version: OpenAFS 1.6.0pre2 built 2011-02-17 (91.pre2....@fnal.gov) admin 82 % vos examine fa11.cs351.backup **** Could not attach volume 536875958 **** RWrite: 536875956 Backup: 536875958 number of sites -> 1 server jeremiah.cs.uwm.edu partition /vicepa RW Site admin 83 % vos examine fa11.cs351 fa11.cs351 536875956 RW 1679 K On-line jeremiah.cs.uwm.edu /vicepa RWrite 536875956 ROnly 0 Backup 536875958 MaxQuota 100000 K Creation Thu Jun 23 20:15:28 2011 Copy Mon Aug 29 11:13:07 2011 Backup Mon Aug 29 13:43:23 2011 Last Access Mon Aug 29 13:33:06 2011 Last Update Mon Aug 29 13:28:10 2011 294 accesses in the past day (i.e., vnode references) RWrite: 536875956 Backup: 536875958 number of sites -> 1 server jeremiah.cs.uwm.edu partition /vicepa RW Site admin 84 % vos remove fa11.cs351.backup vos: Missing required parameter '-id' admin 85 % vos remove jeremiah a fa11.cs351.backup WARNING: Volume 536875958 did not exist on the partition Volume 536875958 on partition /vicepa server jeremiah.cs.uwm.edu deleted admin 86 % vos examine fa11.cs351.backup **** Could not attach volume 536875958 **** Volume fa11.cs351.backup does not exist in VLDB RWrite: 536875956 number of sites -> 1 server jeremiah.cs.uwm.edu partition /vicepa RW Site admin 87 % vos zap jeremiah a fa11.cs351.backup -force -verbose vos: forcibly removing all traces of volume 536875958, please wait...done. admin 88 % vos examine fa11.cs351.backup Could not fetch the information about volume 536875958 from the server : No such device Volume fa11.cs351.backup does not exist Dump only information from VLDB fa11.cs351 RWrite: 536875956 number of sites -> 1 server jeremiah.cs.uwm.edu partition /vicepa RW Site admin 89 % vos backup fa11.cs351 Failed to clone the volume 536875956 Volume not attached, does not exist, or not on line Error in vos backup command.
