Hi I'm trying to unregister disks to unload the bcache module and reuse the disk for other tests. Can someone tell me how to unload module bcache after having run these command ? Thanks. #first load module # modprobe bcache I created a cache device on /dev/sdb1 # ./make-bcache -C -b512k -w4k --writeback /dev/sdb1 and a backing device on /dev/sdz. # ./make-bcache -B /dev/sdz # ./probe-bcache /dev/sdb1 5f42bdd1-4342-4ab6-8dda-855989a09604: UUID="" TYPE="bcache" # ./probe-bcache /dev/sdz 6bbac9a4-afbd-4d40-9562-cdd290622c5d: UUID="" TYPE="bcache" I then registered them by: # echo /dev/sdb1 >/sys/fs/bcache/register # echo /dev/sdz >/sys/fs/bcache/register I have /dev/bcache0. /dev/bcache0 maps /dev/sdz except the first blocks /dev/bcache0 is not yet cached by anything # ls /sys/fs/bcache/ 887d3bb6-0161-4e54-b9d8-801de9f7df83 register register_quiet "887d3bb6-0161-4e54-b9d8-801de9f7df83" is the id of the bcache "pool" composed by the only caching device /dev/sdb1 # now I attach /dev/sdz to this pool echo "887d3bb6-0161-4e54-b9d8-801de9f7df83" > /sys/block/sdz/bcache/attach -- Alain Spineux | aspineux gmail com Monitor your iT & Backups | http://www.magikmon.com Free Backup front-end | http://www.magikmon.com/mksbackup Your email 100% available | http://www.emailgency.com -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
