Maybe your Unix team can help next time :)

Yep, that's it. I learned something new today.

Thank you very much!

Try df -i - it sounds like you may have run out of i-nodes.

I could not run a man page because it couldn't create a temp file.

One of the reasons I never ran hobbit/xymon in the root filesystem - xymon can create a very large number of small files, and this can eat i-nodes faster than it eats disk space. Depending on OS and local preference, I'd suggest making an /opt or /usr//local filesystem with a higher number of i-nodes per block and run xymon in that filesystem.

Anyone have any idea why this might have happened?

Thanks, Dan

Hmm... Murphy's law... As soon as I reach out for help, I find something that might work.

I'm going to try setting fs.file-max=301472 in /etc/sysctl.conf to increase what must be the default of 101472 for the ext3 filesystem on this version of linux.

Unless someone has a better idea?

Ok, I'm running openSuse 11.1 and I'm not finding a way to increase my inodes without doing something drastic like rebuilding from scratch. Lots of freebsd info on the web to increase maxfiles but nothing specific for openSuse.

Can you help?

Thanks!

To the best of my knowledge, the only Linux filesystem that handles this well is reiserfs and that's been deprecated. The only way to set the inode ratio is at file system create/format time. So in your case, this is indeed a "do- over'. And you will not want to set the bytes per inode up significantly on root (/), /usr, or /tmp - which is why I suggested /opt or /usr/local as filesystems to run xymon.

Tom

Thanks for the help!

I was able to give myself some time by writing a script to enter all my server directories and kill all my msgs files since they were taking up 65% of my inodes.

I'll take your advice when I upgrade to xymon and rebuild with your suggested disk configuration.

Thanks again, Dan

Apparently GMail does not strictly follow what looks to be RFC 822. I think a lot of companies go for what is most convenient to the user over what is most correct/predictable.

If you go for the message source, you'll see the "In-reply-to:" header which most mail readers will observe.

One more thing to consider for future reference is that a percentage (default 5% for ext2/3) of the available space will be reserved for root. So you may show some free space but the xymon user can not use any of it.
