Hello Thomas, For several weeks new, I'm trying to install luster 2.2 on debian squeeze server. From what I've observed, the problem seems to be the creation of the files system "mgs/mdt" and then mount. The error message about the file /etc/mke2fs.conf, seems like a "warning". To avoid this, vast with adding a new line in the file, like this:
ldiskfs = { blocksize = 4096 } Initially, to create the file system "MGS/MDT," we must run mkfs.lustre avoiding default option "dirdata", which is not covered by the current version 2.2: $ mkfs.lustre --fsname=lustrefs --mdt --mgs --reformat --mkfsoptions="-E stripe-width = 2-i 4096-O ^ dirdata" --failnode=mdserver-1 --mgsnode=mdserver-0@tcp0 /dev/sdc1 After creating the system successfully, the next problem comes when committing mount the new filesystem: $ mount -t luster /dev/sdc1 /mgs It seems that the whole problem is loading the kernel module fsfilt_ldsikfs, which is dependent of "ldiskfs": $ modprobe fsfilt_ldiskfs FATAL: Error inserting fsfilt_ldiskfs (/ lib/modules/2.6.32-lustre-2.2/updates/kernel/fs/lustre/fsfilt_ldiskfs.ko): Unknown symbol in module, or unknown parameter (see dmesg) Running "dmesg", we note the following: $ dmesg ... [81314.051179] fsfilt_ldiskfs: Unknown symbol jbd2_log_start_commit As we can see, there are a symbol required that is not implemented in the module. This is the key to the problem. I guess solving this, we get to create completely server Lustre MGS … Any idea if someone has managed to create the appropriate patch??? thanks _____________________________________________ Jose Angel Herrero Velasco Dto.
