Re: Question: Maximum number of directories?

Note: I am reposting this to the list where I guess you wanted to
reply to. I hope you don't mind. Please don't send copies to me
directly, I am reading the list.

You probably won't need to reinstall. You just should be prepared to
reformat the partition where MySQL puts its data in case the filesystem
is too slow.

Default is ext3, I think. You can check with 'mount'. I have:

$ mount | grep hda
/dev/hda1 on / type ext3 (rw,errors=remount-ro)
/dev/hda5 on /home type xfs (rw)
/dev/hda3 on /srv type ext3 (rw)
/dev/hda6 on /var type xfs (rw)

You can see that / and /srv are ext3 and /var and /home are xfs. I
chose xfs for these because they contain directories with a lot of
files (the already mentioned Maildirs and a news spool). So far, I had
no problems with xfs.
