I'd like to do an online resize of and XFS filesystem on a non-partitioned device. But, I always have to reboot to do so.
Say I have a sdc with 16777216 blocks and expand it on the SAN to have 17825792 blocks, and rescan the device.
The xfs_growfs does not see the size, nor does blockdev --getsz /dev/sdc, however, the I know the rescan worked because /sys/block/sdc/size now is 17825792 instead of 16777216.
Is there some reason for this? Is there a fix for it? I'm not using any volume management stuff yet but would like to be able to grow our filesystems without having to reboot to do so.
