[zfs-discuss] Problem with ZFS and ACL with GDM

2008-12-05 Thread Brian Cameron
I am the maintainer of GDM, and I am noticing that GDM has a problem when running on a ZFS filesystem, as with Indiana. When GDM (the GNOME Display Manager) starts the login GUI, it runs the following commands on Solaris: /usr/bin/setfacl -m user:gdm:rwx,mask:rwx /dev/audio /usr/bin/setfac

I see this old post about ZFS fragmenting the RAM if it is 32 bit. This makes the memory run out. Is it still true, or has it been fixed? http://mail.opensolaris.org/pipermail/zfs-discuss/2006-July/003506.html -- This message posted from opensolaris.org __

In theory, with 2 80GB drives, you would always have a copy somewhere else. But a single drive, no. I guess I'm thinking in the optimal situation. With multiple drives, copies are spread through the vdevs. I guess it would work better if we could define that if copies=2 or more, that at leas

With ZFS, we can enable copies=[1,2,3] to configure how many copies of data there are. With copies of 2 or more, in theory, an entire disk can have read errors, and the zfs volume still works. The unfortunate part here is that the redundancy lies in the volume, not the pool vdev like with ra
