Zdenek,
I can create new volumes with lvcreate, but after 3 or 4 new volumes my VG pass to inconsistent status because 24 disks stay in missing status, I don't know why. Do you think that the lvm cannot write properly?
My disks are provided by IBM storage DS8000 but I don't have access the configuration. Those devices was working properly until last friday since august 2014.
When I restore my backup with vgcfgrestore, my VG return active without problem, then I believe I don't have problens with write properly. Do you have any idea or a test to do? I cannot shut off this VG now because it's active and used by virtual servers, I have a big problem now.
I created a new VG to create new volumes but I'd like fix this one.
Thanks

Hi Zdenek,
I attached 2 files, one with missing status and another my backup today. I
restored my vg from backup but I still have problem, if I create some new lv
volumes, vg status come back with missing status, I don't know why. Since
saturday night I don't create any volumes in this vg and I don't have any
missing status until now, but I would like come back to create new lv in this
volume.
My server is centos-6.6 with lastest updates.
What are those /dev/mapper/plt-XX devices ?
It seems like the lvm2 command cannot write to this place properly?
Checksum error looks like serious problem.
>From attached output - all your PVs were properly markes as not missing,
however the lvm2 cannot read back proper crc code.
So what are those 0.5GB devices - are they properly writable ?
(especially in the disk header)
Note - there are special type of block devices like DASD devices
that must be first properly configured by IBM storage manager to provide regular devices.
Regards
Zdenek
