-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Well for the seasoned regulars on the list you may already know about this but as it turned out I didn't. Therefore, I'm posting this just so that it may help another LVM newbie. The problem of the kernel dying when the snapshot overflowed was fixed by going to kernel 2.4.17-xfs and using the self generating lvm-1.0.1-2.4.16.patch and the VFS-lock patch. The other problem of ext3 and resierfs not being able to mount a snapshot was fixed by changing the following line in "linux/drives/md/lvm.c" from: /* lvm_do_lv_create calls fsync_dev_lockfs()/unlockfs() */ /* #define LVM_VFS_ENHANCEMENT */ to: /* lvm_do_lv_create calls fsync_dev_lockfs()/unlockfs() */ #define LVM_VFS_ENHANCEMENT More info can be found here: http://marc.theaimsgroup.com/?l=linux-lvm&m=98276596902838&w=2 Hope this helps.

Using the latest XFS CVS + the vfs-lock patch everything seemed fine except if a snapshot ever got full it would oops the machine. Because the LVM version in the XFS CVS is 1.0.1-rc4(ish) I decided to generate the appropriate 1.0.1 patch and recompile to see if this fixed the problem. The order of patches was: Standard 2.4.17-xfs CVS tree + VFS-lock patch + lvm-1.0.1 self generated patch There were no rejects The problem I have now is that I cannot mount the snapshot - I get the standard "wrong fs type, bad option, bad superblock" etc..... error. Has anyone with the XFS CVS kernel ever come up against this before? This mount error occurs for ext3, reiserfs filesystems. Snapshots on XFS volumes work fine as long as they are done with xfs_freeze. - -- Adrian Head (Public Key available on request.) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE8Kzio8ZJI8OvSkAcRAj75AJ9DvAn+kJUDqwf1qxXUSPsCTdt9PQCeOqV8 zWFBV6wjdItpWeL6Yw9hx00= =Uhhb -----END PGP SIGNATURE-----
