Re: linux flash filesystems and GlusterFS

[Apostolos Manolitzas <manap@xxxxxxxxxxxxxxxxxxxx>]

Hello,

as far as I can see, from the UBIFS Faq http://www.linux-mtd.infradead.org/doc/ubifs.html#L_xattr

UBIFS supports extended attributes if the corresponding configuration option is enabled (no additional mount options are required). It supports the user, trusted, and security name-spaces. However, access control lists (ACL) support is not implemented.

beyond that, no clue if it's working.

Hi.

i am not very familiar with those filesystems you mentioned, but as a rule of thumb, a FS for gluster has to support extended attributes, so, this is a good way to start: check if you can tdo that.

Also, when setting gluster with the recommended configuration, you are supposed to use XFS, and the inodes have to be defined with -i size=512.

If experimenting with other FS, make sure you can set the inode as well, just to be in the safe side.

EXT4 is not a good option right now, just in case you are wondering. Lots of discussion and documentation on those issues in past threads of the list.

Cheers.

Hello all,

I just discovered the GlusterFS while looking for a solution for high availability on our NAND flashes. We use ubifs and jffs2 for filesystem and we would like to apply some high availability strategy to a part of the flash. So has anyone tested GlusterFS with this setup? Is it a viable solution or should we move to an upper layer solution?

thanks for any opinion,
