Can anyone explain to me what this means and why I had to manually activate this (and one other) snapshot after a reboot:

Perhaps you had made more changes to the original LV than the snapshot could hold? What does 'lvs <VG name>' show in your system? A quick test in mine with a full 100M snapshot of home: darkside:~ # lvs sys /dev/sys/home-snap: read failed after 0 of 4096 at 42945413120: Input/output error /dev/sys/home-snap: read failed after 0 of 4096 at 42945470464: Input/output error /dev/sys/home-snap: read failed after 0 of 4096 at 0: Input/output error /dev/sys/home-snap: read failed after 0 of 4096 at 4096: Input/output error LV VG Attr LSize Pool Origin Data% Move Log Copy% Convert home sys owi-aos-- 40.00g home-snap sys swi-I-s-- 100.00m home 100.00 root sys -wi-ao--- 20.00g tmp sys -wi-ao--- 10.00g var sys -wi-ao--- 10.00g darkside:~ # darkside:~ # lvdisplay sys/home-snap /dev/sys/home-snap: read failed after 0 of 4096 at 42945413120: Input/output error /dev/sys/home-snap: read failed after 0 of 4096 at 42945470464: Input/output error /dev/sys/home-snap: read failed after 0 of 4096 at 0: Input/output error /dev/sys/home-snap: read failed after 0 of 4096 at 4096: Input/output error --- Logical volume --- LV Path /dev/sys/home-snap LV Name home-snap VG Name sys LV UUID QwG4O9-1gFV-C3s3-TDI2-SMqU-k5yH-TG01Rf LV Write Access read/write LV Creation host, time darkside.localnet, 2013-10-24 21:14:40 +0300 LV snapshot status INACTIVE destination for home LV Status available # open 0 LV Size 40.00 GiB Current LE 10239 COW-table size 100.00 MiB COW-table LE 25 Snapshot chunk size 4.00 KiB Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:17 Didn't get the 'NOT available' LV status though, not even after reboot. -- Martti -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
