version 2.2.0

Support for networks:

o2iblnd - OFED 1.5.4

Server support for kernels:

2.6.32-220.4.2.el6 (RHEL6)

Client support for unpatched kernels:

2.6.18-274.18.1.el5 (RHEL5)
2.6.32-220.4.2.el6 (RHEL6)

Recommended e2fsprogs version:

1.41.90.wc4

Known Issues in 2.2.0:

LU-1188 Panics can occur running sanity test while running with kernel debug options turned on
LU-1191 Due to a known NFS-related bug in the kernel - https://bugzilla.kernel.org/show_bug.cgi?id=38572 - users wanting to re-export Lustre via NFS should apply the kernel patch for this issue
LU-1244 MDS survey tool has a known problem of not deleting OST objects when run in unlink mode, which might lead to unexpected space and inode shortage on OSTs in case of multiple runs
