ceph-deploy and journal on separate disk

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi.

I have some problems with create journal on separate disk, using ceph-deploy osd prepare command.

When I try execute next command:

ceph-deploy osd prepare ceph001:sdaa:sda1

where:

sdaa – disk for ceph data

sda1 – partition on ssd drive for journal

I get next errors:

========================================================================================================

ceph@ceph-admin:~$ ceph-deploy osd prepare ceph001:sdaa:sda1

ceph-disk-prepare -- /dev/sdaa /dev/sda1 returned 1

Information: Moved requested sector from 34 to 2048 in

order to align on 2048-sector boundaries.

The operation has completed successfully.

WARNING:ceph-disk:OSD will not be hot-swappable if journal is not the same device as the osd data

mount: /dev/sdaa1: more filesystems detected. This should not happen,

       use -t <type> to explicitly specify the filesystem type or

       use wipefs(8) to clean up the device.

 

mount: you must specify the filesystem type

ceph-disk: Mounting filesystem failed: Command '['mount', '-o', 'noatime', '--', '/dev/sdaa1', '/var/lib/ceph/tmp/mnt.ek6mog']' returned non-zero exit status 32

 

Someone had a similar problem?

Thanks for the help
