Dear list, Since I couldn't find any clue to what is wrong with my system (or lvcreate?) [searched list archives, Google, how-to] someone reading this list might be able to help me or give me a hint. The Problem: Creating snapshots will fail under certain circumstances: a) the snapshot is > 512MB (fails in aprox. 99.9%), b) the snapshots is < 512MB (fails in aprox. 0.1%). I can't figure out, why creating of >512MB snapshots in rare cases does not fail. # lvcreate -L516M -s -n mysnap /dev/system/lv_home LV system/mysnap in use: not removing Couldn't deactivate new snapshot. /dev/sysem/ shows mysnap. But I can't mount it (mount: filesystem unknown). # lvdisplay --- Logical volume --- LV Name /dev/system/mysnap VG Name system LV UUID LUVE4M-wC4g-YqhI-2gw4-wgfq-P2G0-2k82Ih LV Write Access read/write LV Status available # open 0 LV Size 516,00 MB Current LE 129 Segments 1 Allocation inherit Read ahead sectors 0 Block device 253:7 Executing lvcreate -vvv does not help. Syslog might be of help: if creation fails, I only get one entry: /etc/hotplug.d/block/50-hwscan.hotplug[16398]: new block device /block/dm-7 If creation does not fail, it will show up four entries: /etc/hotplug.d/block/50-hwscan.hotplug[16540]: new block device /block/dm-7 /etc/hotplug.d/block/50-hwscan.hotplug[16582]: new block device /block/dm-8 /etc/hotplug.d/block/50-hwscan.hotplug[16621]: new block device /block/dm-7 /etc/hotplug.d/block/50-hwscan.hotplug[16611]: new block device /block/dm-9 My distribution: SuSE 9.3 on two S-ATA drives. If I can give any further information, please let me know. Thanks in advance.
