Hi Guys
I have a query.
My exisiting storage server (used for media) has 10.7TB usable space (7 x 2TB drives in Raid5 via MDADM, formatted as EXT4, running in Ubuntu Server)
My Backup storage server (exact copy of main server above) has 10.9TB usable space (9 x 1.5TB drives in Raid-Z via Openindiana).
I have copied 9.04Tb from Main server to the ZFS backup server, where it only takes up 8.52TB. The file count is the same, hidden files are viewable.
Now is this that ZFS is that much more efficient? Could it be the ZFS de-duplication, or is there a problem with mdadm or do I have orphan files somewhere?
Im trying to get a solid answer to help me decide which route to take in the future as I am nearing upgrade time.
Im wondering if there are any tools that will help, can you tell what zfs has deduplicated?
Is there anyway to see where that space is being used up (only have CLI or web interface as option)?
Any advice would be appreciated
