Hiya.
I'd like to use amd(8) to automatically mount and dismount local file
systems. The file systems in question are big, lots of complicated
links, lots of files, and take a while to fsck if the power goes out
unexpectedly, and are used relatively rarely (maybe an hour a day).
Sounds like a perfect job for amd(8)!
The file systems in question are mounted to /v/1 and /v/2
I've got the following set up:
$ cat /etc/rc.conf.local
amd_flags=-l syslog -x all -c 10 -w 10
lockd_flags=
portmap_flags=
$ cat /etc/amd/master
/v amd.v
$ cat /etc/amd/amd.v
1 type:=ufs;dev:=/dev/sd2i
2 type:=ufs;dev:=/dev/sd2j
AND....it works!
start the system up, I get this:
$ df
Filesystem 512-blocks Used Avail Capacity Mounted on
/dev/sd2a 1011676 203812 757284 21% /
/dev/sd2h 10319836 48 9803800 0% /home
/dev/sd2f 4136828 20 3929968 0% /tmp

/dev/sd2e 2065116 2104 1959760 0% /usr/local
/dev/sd2g 4136828 64920 3865068 2% /var
amd:36583 0 0 0 100% /v
$ ls /v/1/
[...expected output from files and directories on that file system...]
$ df
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/sd2a 505838 83602 396946 17% /

Success!!
well...no. Seems it never umounts the amd file systems. And that is
basically the point of this exercise -- to increase the odds that a FS
isn't mounted when the power goes out.
Am I doing something wrong? Do I have inaccurate expectations of
what amd(8) does with local file systems?
Nick.
