Hello list,
i'm testing KVM with qemu, libiscsi, virtio-scsi-pci and scsi-general on
top of a nexenta storage solution. While doing mkfs.xfs on an already
used LUN / block device i discovered that the unmapping / discard
commands mkfs.xfs sends take a long time which results in a lot of
aborted scsi commands.
Would it make sense to let mkfs.xfs send these unmapping commands in
small portations (f.e. 100MB) or is there another problem in the patch
to the block device? Any suggestions or ideas?
Thanks!
Greets,
Stefan
