Hello to all,
I'm looking for a solution to enable/disable softupdates without:
1. using single user mode
2. changing filesystem status, e.g.:
mount -ufo ro <filesystem>
tunefs -n enable <filesystem>
mount -ufo rw <filesystem>
1. is problematic for those who don't have console access to
machine/server
2. can result in several errors in filesystems like /var
To enable softupdates in a filesystem, we need to have a filesystem
unmounted (or in reed-only mode) so I used rc script to enable it
before the system mounts all filesystems.
I've changed rc (line 217 - 4.6-PRERELEASE) to:
### /etc/rc
(...)
# If using diskless, run custom disk mounting function here
#
if [ -n "${diskless_mount}" -a -r "${diskless_mount}" ]; then
sh ${diskless_mount}
else
# otherwise mount everything except nfs filesystems.
+ #SOFTUPDATES ENABLE/DISABLE BEFORE MOUNTING ALL FILESYSTEMS -
+
+ case ${softupdates_enable} in
+ [Nn][Oo][Nn][Ee] | '')
+ # do nothing
+ ;;
+ [Yy][Ee][Ss])
+ # enable softupdates in fs list
+ for sufs in ${softupdates_fs}; do
+ tunefs -n enable ${sufs}
+ done
+ ;;
+ [No][Oo])
+ # disable softupdates in fs list
+ for sufs in ${softupdates_fs}; do
+ tunefs -n disable ${sufs}
+ done
+ ;;
+ esac
mount -a -t nonfs
fi
(...)
and add 2 config lines to rc.conf:
### /etc/rc.conf
+ softupdates_enable="NONE" # YES - Enable; NO - Disable; NONE - Nothing
+ softupdates_fs="/dev/ad0s1d /dev/ad0s1h"
It works ok but this method is stupid because we need to activate
softupdates only once and not every time that we reboot/start the machine.
Does anyone knows a better way of doing this?
Thanks,
Nuno Teixeira
