[Lustre-discuss] MDS_with_ZFS_DMU

[Arden Wiebe]

Without having checked through the cvs is this the preferred method of implementing Lustre?  I am RTFM at every opportunity and implementing on my boxes here to develop a growing cluster.  So far I have the latest 1.6 installed but not really working on one machine.

  Permanent disk data:
Target:     spfs-MDTffff
Index:      unassigned
Lustre FS:  spfs
Mount type: ldiskfs
Flags:      0x75
              (MDT MGS needs_index first_time update )
Persistent mount opts: errors=remount-ro,iopen_nopriv,user_xattr
Parameters: mdt.group_upcall=/usr/sbin/l_getgroups

checking for existing Lustre data: not found
device size = 953869MB
2 6 18
formatting backing filesystem ldiskfs on /dev/sdb
        target name  spfs-MDTffff
        4k blocks     0
        options        -J size=400 -i 4096 -I 512 -q -O dir_inde
mkfs_cmd = mkfs.ext2 -j -b 4096 -L spfs-MDTffff  -J size=400 -i
Writing CONFIGS/mountdata

Fun stuff.  Installed the 

[root at localhost Desktop]# rpm -ivh lustre_admin-2-0_2007_09_28_Friday_09h49m25s.noarch.rpm

although I haven't figured out how to start it yet.  Wanting to install the kernel, modules and tools for the subject matter assuming it is the way to proceed and bypass 1.6 branch.
