[Pkg-lustre-maintainers] Installing Lustre 2.2.0 on Debian Squeeze

[Jose Angel Herrero Velasco - IMAP]

Indeed Thomas,

we are currently working on Linux Debian squeeze, so could you provide me the source code for the Whamcloud e2fsprogs (version 1.42.3), please???

About the problem that I described in the previous mail with the kernel module fsfilt_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

know any solution about it???

thanks in advance
