I have a machine with 4 gb ram, and 4 gb swap, and it's all been
eaten up by xfs_repair, and slowed down to a crawl.

the sdc partition is the one being checked. i am all out of memory
now. 4 gb phys and 4 gb swap all gone.


posted to pastebin for better formatting.

i was using:

[root@kp4 ~]# xfs_repair -o bhash=16384 -o ihash=16384 -o
ag_stride=16 \
  > /dev/sdc >& /tmp/repair.log

but now i am trying the -m option to see if the memory can be
limited, so the server doesn't freeze.

Or maybe you could turn the swap off entirely for the check. Apparently
all of the IOs are going to sda, which I suppose hosts the swap.
