/ FS remounting read-only

general

I've been experiencing a rather annoying problem with the / partition on my Linode. Periodically, and only when I'm downloading with Bit Torrent, the filesystem gets remounted read-only. Of course, this being the logging partition, the error that causes this isn't logged either.

My suspicions are one of:

  • Too much disk i/o

  • Somehow the partition is trying to write outside where it should – some bug in the disk resizing with linode?

I've e2fsck'ed the partition, correcting any errors, but the problem recurs whenever I run Bit Torrent.

Any ideas? Or ideas how I can at least diagnose the problem?

Maybe try logging to a different partition, or remote logging to another host?

EDIT: Or log to the console?

Or maybe look at the output of````

dmesg

````

I used to have a similar problem that would occur during backups. It was all related to the partition using 1K blocks instead of 4K. See this thread:

Yes this does seem to be the 1k block size bug. Linode have a (currently unlinked) utility to convert your fs. I raised a ticket and (fast as ever) Mike responded and got it all happening for me.

Thanks guys! Insanely good support, as always.
