Zdenek,

My multipath devices have= an alias to plt-XX instead of the default name mpathXX.=C2=A0

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 un= til last friday since august 2014.

When I restore = my backup with vgcfgrestore, my VG return active without problem, then I be= lieve I don't have problens with write properly. Do you have any idea o= r a test to do? I cannot shut off this VG now because it's active and u= sed 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

=C2=A0

Hi Zdenek,

I attached 2 files, one with missing status and another my backup today. I<= br> restored my vg from backup but I still have problem, if I create some new l= v
volumes, vg status come back with missing status, I don't know why. Sin= ce
saturday night I don't create any volumes in this vg and I don't ha= ve any
missing status until now, but I would like come back to create new lv in th= is
volume.
My server is centos-6.6 with lastest updates.



 What are those=C2=A0 /dev/mapper/plt-XX=C2=A0 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 re= gular devices.

Regards


Zdenek
