From 9ed96484311b89360b80a4181d856cbdb21630fd Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Mon, 31 Jan 2011 14:32:14 +0200 Subject: exofs: Add option to mount by osdname If /dev/osd* devices are shuffled because more devices where added, and/or login order has changed. It is hard to mount the FS you want. Add an option to mount by osdname. osdname is any osd-device's osdname as specified to the mkfs.exofs command when formatting the osd-devices. The new mount format is: OPT="osdname=$UUID0,pid=$PID,_netdev" mount -t exofs -o $OPT $DEV_OSD0 $MOUNTDIR if "osdname=" is specified in options above $DEV_OSD0 is ignored and can be empty. Also while at it: Removed some old unused Opt_* enums.
