After a power outage we encountered a hardware error on one of our storage devices that essentially corrupted ~30 files on one of the OSTs. Since then the OST has been read-only and is throwing the following log messages:

[ 351.029519] LustreError: 8974:0:(ofd_obd.c:1376:ofd_create()) fscratch-OST0001: unable to precreate: rc = -5
[ 360.762505] LustreError: 8963:0:(ofd_obd.c:1376:ofd_create()) fscratch-OST0001: unable to precreate: rc = -5
[ 370.784372] LustreError: 8974:0:(ofd_obd.c:1376:ofd_create()) fscratch-OST0001: unable to precreate: rc = -5

I have scrubbed the device in question and rebooted the system bring up the server normally but I am still unable to create a file on that OST.

zpool status -v reports the damaged files and recommended restoring from backup and I'm inclined to simply removing the files. I know how to do this with ldiskfs but I don't know how to with ZFS. At this point I don't know how to proceed.
