- After extending the size of volume from 100gb to 300gb from SAN. Issued the following commands:
# multipath -l mpatha (360a9800064716863476f7350324a7478) dm-8 COMPELNT,Compellent Vol [size=100G][features=1 queue_if_no_path][hwhandler=0][rw] \_ round-robin 0 [prio=0][active] \_ 0:0:1:3 sdg 8:96 [active][undef] \_ 1:0:1:3 sdl 8:176 [active][undef]
# echo 1 > /sys/block/sdg/device/rescan
# multipathd -k"resize map mpatha" fail
# resize2fs -p /dev/mapper/mpatha resize2fs 1.39 (29-May-2006) The filesystem is already 13107200 blocks long. Nothing to do!
# df -h /data Filesystem Size Used Avail Use% Mounted on /dev/mapper/mpatha 100G 56G 40G 59% /app
- Had to reboot to expand mpatha. This is supposed to be done "on-the-fly". Any reason?
- Red Hat Enterprise Linux 5 & 6
