Description lejeczek 2011-02-15 09:59:44 UTC 
Description of problem:

I am sure I've seen it before, there was a certain partition size up to which xfs_check succeeded, cannot remember though, feels like something is wrong deep there in the xfs itself or/and its tool/s

Version-Release number of selected component (if applicable):

xfsprogs-3.1.2-1.fc14.x86_64
2.6.35.11-83.fc14.x86_64

How reproducible:
PV that spans whole device, VG on top of this PV, subsequently LV spans whole VG, SAS2 JBOD using SATA-3 HDDs put together as a hardware RAID0 volume, default mkfs.xfs

yet, tried on different systems having different underlying hardware and process gets killed every time for gobbling too much memory.

Steps to Reproduce:
1.
2.
3.
  
Actual results:


Expected results:

Comment 1 Eric Sandeen 2011-02-15 22:07:38 UTC 
xfs_check is known to not scale, and is on its way to being deprecated.

If you want a check-only filesystem verification, please use xfs_repair -n.

Thanks,
