zfs configuration
Hi All, So I use zfs for the root file system. Works well. However now I want to move /tmp to ram-disk (memory disk or what ever). When I try to unmount /tmp with the zfs command of course it won't because its busy. With ufs I would just edit fstab and reboot what do I don with zfs?? Thx in advance...

Your best option is to reboot into single user mode, however if that's not possible, zfs umount -f will force it to unmount. -- Thanks, Dean E.

Hi All,

I've been moving a lot of machines from 9.0 to 9.1 with some patches
this days (like tmpfs-nrbtree). I inject some code inde /etc/rc.d/zfs to
update this. I'm adding this to /etc/fstab:
tmpfs /tmp tmpfs rw,nosuid 0 0
After this I'm changing /etc/rc.d/zfs:
@@ -23,6 +23,12 @@
zfs_start_main()
{
+ umount /tmp
+ zfs destroy mypool/tmp
+ rm -rf /tmp
+ mkdir -p /tmp
+ chmod ugo+rwxt /tmp
+ mount /tmp
zfs mount -a
zfs share -a
if [ ! -r /etc/zfs/exports ]; then
After reboot zfs filesystem for tmp is gone and tmpfs is in charge.
The code is harmless upon reexecution and just does the job. I haven't
found easier way of doing this.

Stop them, mount a new /tmp, and then restart them. Or use fstat and avoid the lsof overhead -- Adam Vande More ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: zfs configuration
Hi, If you are using different filesystem for /tmp, which I guess you do, I would recommend trying: zfs set mountpoint=/something zfsroot/tmp This way you will change the mountpoint to some other location. Also if you have trouble dismounting the system you can do: 1. fstat to find out which process is using the system; 2. use -f option to force the dismount process. Hope this helps.
