I take a snapshot every hour, every 8 hour, eveyr day, and every week. I've got 4 "equal" scripts to do the work, the only difference is the snapshot name and the mountpoint. However, when i try to remove the old and unmounted snapshot, i sometimes get an error message. Like one in every 10 times. I get messages like: -------------------- lvremove -- can't remove open snapshot logical volume "/dev/optVG/1hour_snapshot_opt_1035237601" And: ---- lvremove -- ERROR "lv_release(): LV number" releasing logical volume "/dev/optVG/1hour_snapshot_opt_1035324001" If i use lvdisplay on them, i get a message like ------------------------------------------------ ve:/dev/optVG# lvdisplay /dev/optVG/1hour_snapshot_opt_1035* lvdisplay -- logical volume "/dev/optVG/1hour_snapshot_opt_1035324001" doesn't exist lvdisplay -- logical volume "/dev/optVG/1hour_snapshot_opt_1035345601" doesn't exist lvdisplay -- logical volume "/dev/optVG/1hour_snapshot_opt_1035352801" doesn't exist lvdisplay -- logical volume "/dev/optVG/1hour_snapshot_opt_1035381601" doesn't exist lvdisplay -- logical volume "/dev/optVG/1hour_snapshot_opt_1035410401" doesn't exist lvdisplay -- logical volume "/dev/optVG/1hour_snapshot_opt_1035432001" doesn't exist lvdisplay -- logical volume "/dev/optVG/1hour_snapshot_opt_1035439201" doesn't exist The problem is that these snapshots take up space. Most take 1GB, since thats what they are created with, but some take more, since i run some scripts to ensure that they dont reach 100% so they are always readable. I can remove the "files" from /dev/optVG/, but the space is not released until i restart the VG. Even restarting the VG doesnt remove the "dead" snapshots (the files in /dev/optVG/) JonB _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
