Since deactivating those 32 "near-full" OSTs on 4/6, we haven't seen the problem on that file system.</p> <p>Consequently, we are now seeing the issue on another file system where OSTs are ~ 90% full.</p> TOSS 2.4-7<br/> lustre-2.5.5-3chaos_2.6.32_573.18.1.1chaos.ch5.4.x86_64.x86_64<br/> ZFS 0.6.5.4-1.ch5.4.x86_64 LU-8007
