Crash running XFS over iSCSI volume
Quoted 5 lines · Bob Gilligan
Hi Folks -- I'm running Linux kernel 2.6.8.1 and version 4.0.1.8 of the Linux initiator. I mounted an XFS filesystem over a 900 GB iSCSI
volume, then ran "bonnie" with the args "-v 5 -o_direct". Within about
30 seconds, the kernel started spewing printks frombad_page(). The first few were:
Kown issues. XFS uses slab pages (as you noticed below), networking code doesn't like that. DRBD has been tripping the same issue. We need to come up with a consensus about what type of pages can be used in block I/O requests. The drbd folks promised to get this discussed on lkml but I haven't seen a discussion yet - so let's do it now.
