Why if i'm under copying some data from remote host to smb share on my server with lvm2 logical volume and 1 or 2 snashots which is/are filled > 1% and at the same time lvremove snapshot then it cause "segmentation fault" and after that all read/write commands to that lv e.g. cp hangs up ? With reference to: " In the meantime, you can apply the snapshot patches in the -udm tree and use 'dmsetup' manually to activate and deactivate snapshots when lvm2 fails. Patches 8 and 9 at: ftp://sources.redhat.com/pub/dm/patches/2.6-unstable/2.6.12-rc2/2.6.12-rc2-udm1/ (Further patches are needed, but those two plus correct dmsetup use should avoid machine lockups.) Alasdair " what does it mean "correct use of dmsetup tool" and when it should be used: before and after lvcreate or lvremove snapshot or with both ? Thanks all for any response, Best regards, Hubert hubgor@poczta.fm ---------------------------------------------------------------------- Jedyny taki czat... >>> http://link.interia.pl/f18b0
