I'm off breaking all the rules here. Here's what I have: Debian backport of 2.4.26 (only change was adding 64G support) Debian stable (1.0.4 it says) I want to use snapshots for backing up oracle, but here's what I have: cliff:~# lvcreate -l1 -s -n oracle_control_1_snap /dev/vg00/oracle_control_1 lvcreate -- INFO: using default snapshot chunk size of 64 KB for "/dev/vg00/oracle_control_1_snap" lvcreate -- doing automatic backup of "vg00" lvcreate -- logical volume "/dev/vg00/oracle_control_1_snap" successfully created cliff:~# mount /dev/vg00/oracle_control_1_snap /snapshot/oracle/ mount: block device /dev/vg00/oracle_control_1_snap is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/vg00/oracle_control_1_snap, or too many mounted file systems cliff:~# (The size of the lv that I'm doing a snapshot of is 1 64M extent, so doing a 1 extent in size should be enough, yes?) My understanding is that this is a result of the VFS patch not being applied. But there doesn't seem to be a VFS patch for 2.4.26. Any ideas? I can provide whatever additional information you need, but this is really strange. -Mark -- Mark Komarinski mkomarinski@hms.harvard.edu Sr. Linux/UNIX System Administrator http://wqcg.med.harvard.edu West Quad Computing Group Harvard Medical School
