My test server was in very eavy load, running kolab's components: postfix, cyrus-imap and openldap A second test machine was sending, and reading emails as fast as it can. The CPU was never idle ! I left the server at about 17H30 and at 22H I find it "uncommitted" (difficult to work when the partition in read-only !) However the mount command report it as RW ! The /boot is still RW for real indeed. some more info [root at c700 trunk]# touch /foo.bar touch: cannot touch `/foo.bar': Read-only file system [root at c700 trunk]# mount /dev/md1 on / type ext3 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/md0 on /boot type ext3 (rw) tmpfs on /dev/shm type tmpfs (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) max:/s0 on /s0 type nfs (rw,addr=192.168.*.*) [root at c700 trunk]# cat /var/log/messages Mar 30 04:02:13 c700 syslogd 1.4.1: restart.
