[linux-lvm] LV crossover problem

[psindelar at mfservis.cz]

Hi,
I have problem with LVM 1.0.3 (shipped with Rh 7.3).
I have 2 VGs, one is at FC FASTt200 shared with 2nd node (it's cluster
configuration 2nodes, LifeKeeper on top of it).
On this VG I have 14 LV....it all worked like a charm until yesterday. 3
lv isn't active (info from /proc/lvm/global) but mount and df
reports,that all fs are mounted. Those three lv's are mixed together with
another 3 lv's in this way: in both mount points are all files form
originating lv and from the crosse one. df reports whole size for the
activated fs but used size is cumulated from both fs.

All filesystems is ext3.

It happend once but after reboot all was back (so fs "splitted") without
any error message. I can't fin any error message which could enlighten me
whats wrong and what I should repair (reboots and takeover to 2nd node
doesn't help).

Is this known bug? Should I try leave RH's lvm and try LVM 1.0.8 from
sistina? Am I risking something?


Thanks
Petr Sindelar
