Yeah, some sacrifice needed.

you have? It's not unusual for xfs_repair to require many GB of
memory to run succesfully on filesystems of this size...
it is around 11 TB, 7.2 used.
I have 4 G ram, but xfs_repair -vv -m1 says I need 1558
root@ws1000:~# xfs_repair -vv -P -m 1 /dev/mapper/vg0-lv0
Phase 1 - find and verify superblock...
- max_mem = 1024, icount = 29711040, imem = 116058, dblock = 2927886336, dmem = 1429632
Required memory for repair is greater that the maximum specified
with the -m option. Please increase it to at least 1558.
so I figured 1750 megs would be enough
