Package: lvm2 Version: 2.02.06-3 Severity: important Starting off with a brand new VG:
[EMAIL PROTECTED]:~ # pvcreate /dev/sda2 Physical volume "/dev/sda2" successfully created [EMAIL PROTECTED]:~ # pvcreate /dev/sda3 Physical volume "/dev/sda3" successfully created [EMAIL PROTECTED]:~ # vgcreate vg /dev/sda2 /dev/sda3 Volume group "vg" successfully created We try to make a mirror LV: [EMAIL PROTECTED]:~ # lvcreate --size 100M --mirrors 1 --name mirrorlv vg Not enough PVs with free space available for parallel allocation. Consider --alloc anywhere if desperate. So I try that: [EMAIL PROTECTED]:~ # lvcreate --size 100M --mirrors 1 --name mirrorlv vg --alloc anywhere Insufficient suitable allocatable extents for logical volume : 50 more required Then I try forcing the two mirror locations: [EMAIL PROTECTED]:~ # lvcreate --size 100M --mirrors 1 --name mirrorlv vg --alloc anywhere /dev/sda2 /dev/sda3 Insufficient suitable allocatable extents for logical volume : 50 more required Then in a final attempt, knowing that really a 2-way mirror wants 3 LVs (one for the loglv as well), I try forcing that: [EMAIL PROTECTED]:~ # lvcreate --size 100M --mirrors 1 --name mirrorlv vg --alloc anywhere /dev/sda2 /dev/sda3 /dev/sda3 Inconsistent length: 1 25 PV segment pe_alloc_count mismatch: 1 != 26 PV segment VG free_count mismatch: 47658 != 47633 Internal error: PV segments corrupted in vg. Ooops. At this point the VG seems stable still. But if I attempt it a second time: [EMAIL PROTECTED]:~ # lvcreate --size 100M --mirrors 1 --name mirrorlv vg --alloc anywhere /dev/sda2 /dev/sda3 /dev/sda3 LV mirrorlv_mlog invalid: segment 2 should begin at LE 1 (found 0).

Volume group for uuid not found: 7GdZGk2PIrCvQ3cFDce2lfw1262UQHyh1ex58nUi9EBWv508q2NhFbwvG90dcMUb Aborting. Failed to activate mirror log. Remove new LVs and retry. Failed to create mirror log. [EMAIL PROTECTED]:~ # vgdisplay LV mirrorlv_mlog invalid: segment 2 should begin at LE 1 (found 0). Couldn't read all logical volumes for volume group vg. LV mirrorlv_mlog invalid: segment 2 should begin at LE 1 (found 0). Couldn't read all logical volumes for volume group vg. LV mirrorlv_mlog invalid: segment 2 should begin at LE 1 (found 0). Couldn't read all logical volumes for volume group vg. LV mirrorlv_mlog invalid: segment 2 should begin at LE 1 (found 0). Couldn't read all logical volumes for volume group vg. Volume group "vg" not found So far the only way I've found out of this is to vgchange -a n, then remove and recreate the VG from scratch. Admittedly [the above] isn't a very usual way of working, but it really shouldn't irreversablly corrupt the VG like that. -- System Information: Debian Release: testing/unstable APT prefers testing APT policy: (990, 'testing'), (500, 'unstable') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.16-mh3.nim Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Versions of packages lvm2 depends on: ii debconf [debconf-2.0] 1.5.5 Debian configuration management sy ii libc6 2.3.6.ds1-4 GNU C Library: Shared libraries ii libdevmapper1.02 2:1.02.08-1 The Linux Kernel Device Mapper use ii libncurses5 5.5-3 Shared libraries for terminal hand ii libreadline5 5.1-7 GNU readline and history libraries ii libselinux1 1.30.28-2 SELinux shared libraries ii libsepol1 1.12.26-2 Security Enhanced Linux policy lib ii lvm-common 1.5.20 The Logical Volume Manager for Lin lvm2 recommends no packages. -- debconf information excluded -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
