Hello, This problem discussed before, but there were no solution for me. I patched 2.6.18 vanilla kernel, and installed lustre modules (ver: 1.6.4.2) successfully. I am giving this command to construct mds: mkfs.lustre --mdt --mgs --fsname=large-fs /dev/sda1 but it gives me this error: ---- mkfs.lustre: Unable to mount /dev/sda1: No such device Is the ldiskfs module available? mkfs.lustre FATAL: failed to write local files mkfs.lustre: exiting with 19 (No such device) ---- here is the result of "modprobe -v ldiskfs" command: ---- insmod /lib/modules/2.6.18/kernel/fs/lustre-ldiskfs/ldiskfs.ko FATAL: Error inserting ldiskfs (/lib/modules/2.6.18/kernel/fs/lustre-ldiskfs/ldiskfs.ko): Unknown symbol in module, or unknown parameter (see dmesg) ---- and for "dmesg | grep ldiskfs": ---- ldiskfs: Unknown symbol __d_move ldiskfs: Unknown symbol __d_move ldiskfs: Unknown symbol __d_move ldiskfs: Unknown symbol __d_move ldiskfs: Unknown symbol __d_move ldiskfs: Unknown symbol __d_move ---- How can I solve this problem ? (needless to say, of course I have /dev/sda1) Thanks in advance -------------- next part -------------- An HTML attachment was scrubbed...
