We didn't have anything in place to capture the console logs and I wont be able to provide you any specific details of the kernel panic at this time.
The kernel panic was easily reproducible with Lustre 1.6.7 on lustre patched kernel(RHEL5) as well as 2.6.22.14 kernel. In our configuration we have a separate machine which hosts the MDT and MGS with each having their own partition. There are 2 OSSs and each OSS exports 6 OSTs amd each OST is 2.7TB in size. The MDT/MGS machine crashed consistently when I tried to mount the 5 or 6th(out of 12) OST. This is the setting on MGS, MDT and all the OSTs that produces the kernel panic. tunefs.lustre --erase-params --mgs --param lov.stripecount=1 --writeconf /dev/mapper/lustre1_volume-mgs_lv tunefs.lustre --erase-params --mdt --mgsnode=lustre1 at tcp1 --param lov.stripecount=1 --writeconf --param mdt.quota_type=ug /dev/mapper/lustre1_volume-new_mds_lv tunefs.lustre --erase-params --ost --mgsnode=lustre1 at tcp1 --param ost.quota_type=ug --writeconf /dev/sdc1 Our file system is in production use right now and I wont be able to take a downtime to reproduce this problem. Please let me know if I can provide you any other detail at this time.
