JFS only creates entries in /proc/fs/jfs when CONFIG_JFS_DEBUG is enabled in the kernel. We should create some entries when CONFIG_JFS_STATISTICS is defined and CONFIG_JFS_DEBUG is not, but it's not working that way right now. You just reminded me we need to fix this. > By the way: whenever I untar something big on a jfs volume I notice a > very big decrease in performance on any other jfs filesystem. > For example: > /usr Is a separate evms volume and /home is as well (so are /, /var, > /tmp, /boot ..., but that's not important) > > When I untar something to /usr/src and edit something in my homedir > and try to save it, it often takes a lot of time before I can > continue working. Is this normal behaviour ? I'm guessing this is due to serialization in the jfsCommit kernel thread. I'll look into creating one such thread for every filesystem and see if it improves things. > Thanks again, > Bas.
