Hello everyone,

I have this message appear about 3-5 times a week (interesting enough, always around 2:15am every Monday like clockwork) that knocks out my NFS mount to a NAS device. I receive the following message in syslog:

modprobe: modprobe: Can’t locate module block-major-65.

The message will repeat with modprobe errors for block-major-[66, 67, 68, 69, 70, 71, 128, 129, 130, 131, 132, 133, 134, 135] in a row [all the messages appear in the same time/second]

At the same time this happens, it knocks out my NFS mount to a NAS device. For example, last Monday -- I received the message “nfs: warning: mount version older than kernel” and “NFS: mount program didn’t pass remote address!” on the console when these modprobe messages appears in syslog for one second. I think the modprobe is causing the issue, thus NFS is collateral damage.

Could anyone give me any background on what might be causing it? (The timing, every Monday at 2:15am makes me think that some scheduled job [cron] is doing something but I don’t see evidence of that)… Anything on what I can do and why it would take out my NFS mount.

I am currently running Red Hat Enterprise Linux AS Release 3 (Update 7) and have Compaq/HP DL360 G3...I’m using modutils-2.4.25-14.EL and kernel level is 2.4.21-37EL

Thanks in advance for your response(s)!

You could check if it's aliased "modprobe -c|grep block-major-65" or "grep block-major-65 /usr/src/linux/Documentation/devices.txt" or search LQ for similar error messages to see if it's something you (don't) have or need. There's also the adventurous way, bypassing all that "research" and just adding the appropriate "alias block-major-device_nr off" lines in modules.conf and *then* see what breaks :-]
