It looks like your root filesystem was not unmounted cleanly. Perhaps something went wrong during the shutdown of the guest. You may be able to get around this by mounting it r/w, then unmount and mount it r/o.
In general I don't like to use journaled filesystems for read only access. It seems like they will try to write to the journal even when the filesystem is mounted read only. -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of Peter E. Abresch Jr. - at Pepco Sent: Wednesday, December 29, 2004 1:25 PM To: [email protected] Subject: basevol/guestvol w/ Reiserfs or ext2 opinions I think I know the answer but appreciate any confirmations or other recommendations. It has been a long process. I am attempting to implement a basevol/guestvol system similar to what is described at http://linuxvm.org/present/misc/basevol.html . I have the root filesystem defined as R/O under z/VM. When I try to boot, it fails rather quickly with the following: end_request: I/O error, dev 5e:01 (dasd), sector 65680 reiserfs: journal-837: IO error during journal update Replay Failure, unable to mount sh-2022: reiserfs_read_super: unable to initialize journal space Kernel panic: VFS: Unable to mount root fs on 5e:01 HCPGIR450W CP entered; disabled wait PSW 000A0000 80230D08 Yes, I use Reiserfs and it appears I overlooked a minor detail with the journaling. Am I correct in the assumption that the basevol/guestvol system will not work with reiserfs? Would ext2 be a better choice for what I am trying to accomplished? As always, thank in advance.
