No LVM on loopbackNo LVM on loopbackPosted Apr 24, 2008 20:32 UTC (Thu) by nix (subscriber, #2304)In reply to: No LVM on loopback by zlynx Parent article: Benchmarking Linux filesystems on software RAID 1 (Lone Wolves)
It is, but still... the problem is apparently that the lvm tools don't lock themselves in memory, and there's a window where I/O to the snapshot origin is disabled. If the OS needs to page in the LVM tools at that point, deadlock. (And that's only the known deadlock.)
