[dm-devel] pvmove/mirror target mirroring data between two devices with different sector size

[Liuhua Wang]

Hi List,

I have a question that I think maybe you can give me some idea.

I have two devices with different sector size: 512B and 4096B.

- SOURCE DEVICE (mdos lvm partiton)
#parted /dev/sdb
Model: ATA SATADOM-SL 3ME (scsi)
Disk /dev/sdb: 32.0GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
(In `parted` Sector size are both got from IOCTL(BLKSSZGET))

- TARGET DEVICE (WHOLE DISK)
#parted /dev/sdc
Error: /dev/sdd: unrecognised disk label
Model: ATA HUH728080ALN600 (scsi)
Disk /dev/sdd: 8002GB
Sector size (logical/physical): 4096B/4096B
Partition Table: unknown

I want to move data from one device to the other using lvm command
`pvmove`, but after pvmove, file system cannot mount.

So my question is whether pvmove support moving date between devices with different sector size
or same question: mirror target support mirroring data between two devices with different sector size?

Thank you in advance.

Best regards,
Liuhua
