[SOLVED] Default file system?

[sshaikh]

According to the documentation I've read and searched for, ext3 is supposedly the default filesystem for proxmox installations. However on installing 4.4-1, it seems that it actually uses ext4.

Filesystem Type 1K-blocks Used Available Use% Mounted on
udev devtmpfs 10240 0 10240 0% /dev
tmpfs tmpfs 3257328 9100 3248228 1% /run
/dev/dm-0 ext4 30316572 1243796 27509744 5% /
tmpfs tmpfs 8143316 37440 8105876 1% /dev/shm
tmpfs tmpfs 5120 0 5120 0% /run/lock
tmpfs tmpfs 8143316 0 8143316 0% /sys/fs/cgroup
/dev/sdb2 vfat 258095 292 257803 1% /boot/efi
/dev/fuse fuse 30720 16 30704 1% /etc/pve

Has the default been changed? Or am I reading the above incorrectly?

Is ext3 still recommended? Is there any advantage to reinstalling proxmox and manually selecting ext3 on installation?

ext3 was the default on proxmox 3.X, mainly for openvz quotas if I remember.

since proxmox 4.X it's ext4 by default. (because no more openvz=

Thank you for the prompt reply. I'm not sure if its worth documenting this?

Also is there a reason why ext4 was chosen? The same searches above seemed to indicate that ext3 was a better choice...

ext4 is the default and recommended.

but you can still use ext3 is you believe this is better, but I do not see any technical reason why ext3 is better.

if you care about your data integrity, ZFS is the way to go.
