Hi. Any changes (

Can you create a build that passes the -t flag with mount?

The separate commands (e.g. `ceph-disk -v prepare /dev/sda1`) works because then the journal is on the same device as the OSD data, so the execution is different to get them to a working state.

I suspect that there are left over partitions in /dev/sdaa that are causing this to fail, I *think* that we could pass the `-t` flag with the filesystem and prevent this.

Just to be sure, could you list all the partitions on /dev/sdaa (if /dev/sdaa is the whole device)?

Something like:

    sudo parted /dev/sdaa print

Or if you prefer any other way that could tell use what are all the partitions in that device.

 

 

After

ceph-deploy disk zap ceph001:sdaa ceph001:sda1

 

root@ceph001:~# parted /dev/sdaa print

Model: ATA ST3000DM001-1CH1 (scsi)

Disk /dev/sdaa: 3001GB

Sector size (logical/physical): 512B/4096B

Partition Table: gpt

 

Number  Start  End  Size  File system  Name  Flags

 

root@ceph001:~# parted /dev/sda1 print

Model: Unknown (unknown)

Disk /dev/sda1: 10.7GB

Sector size (logical/physical): 512B/512B

Partition Table: gpt

So that is after running `disk zap`. What does it say after using ceph-deploy and failing?

 

Number  Start  End  Size  File system  Name  Flags

 

After ceph-disk -v prepare /dev/sdaa /dev/sda1:

 

root@ceph001:~# parted /dev/sdaa print

Model: ATA ST3000DM001-1CH1 (scsi)

Disk /dev/sdaa: 3001GB

Partition Table: gpt

 

Number  Start   End     Size    File system  Name       Flags

1      1049kB  3001GB  3001GB  xfs          ceph data

 

And

 

root@ceph001:~# parted /dev/sda1 print

Model: Unknown (unknown)

Disk /dev/sda1: 10.7GB

Sector size (logical/physical): 512B/512B

Partition Table: gpt

 

Number  Start  End  Size  File system  Name  Flags

 

With the same errors:
