How to enable btrfs autodefrag

[dgaglioni]

How can I mount my pool with autodefrag enabled using btrfs?

There's no GUI option for that, you could gave a script doing a remount.

Thank you Jorge,

 

I did a cat on fstab and that's all information I got:

 

[email protected]:~# cat /etc/fstab
/dev/sda1                  /boot         vfat      rw,flush,noatime,nodiratime,dmask=77,fmask=177,shortname=mixed
/boot/bzmodules            /lib/modules  squashfs  ro,defaults
/boot/bzfirmware           /lib/firmware squashfs  ro,defaults
tmpfs                      /dev/shm      tmpfs     defaults
hugetlbfs                  /hugetlbfs    hugetlbfs defaults

 

I was hoping to see the mount options for the pools I have, do you know where I can find it so I can add the autodefrag option?

You can use:

 

mount -o remount -o autodefrag /mnt/pool_name

 

Note that you should not use this if you use snapshots.
