Re: jfs2 log wrapping and monitoring log usage

OK, thanks for that info; still hoping for a tool that reports jfs log activity, instead of a guideline.

well, the error message seems to indicate that
transactions to the jfs2 filesystem were written too
fast for the jfs2log to keep upto them.

somewhere in the network I found a rule of thumb of
4MB of jfs2log per 2GB of data, I tried to look for
that information again today, since I'm creating a
bunch of jfs2 filesystems and wanted to make sure it
is worth keeping a 1Gb jfs2log.

I've got a whole bunch of JFS2 filesystems, all
using the inline
log. I just got the "J2_LOG_WRAP_START" error for
one, and while I
was able to fix it by making the log larger.

I was wondering if there was a command that could be
used to
determine just how much of the log for a given
filesystem is used,
and if it should be enlarged beforehand. Kind of
like a "df" but for
JFS2 logs.
