kouignamann Posted February 21, 2016 #1 Posted February 21, 2016 Hi all, I've recently installed Xpenology (DSM 5.2-5644 Update 5, recognized as a DS3615xs) on a HP Proliant Microserver Gen8 G1610T. Only modification are that I updated everything with latest HP SPP and I disabled "hardware" RAID for SATA AHCI instead giving direct access to disks. It works great so far. I'm almost done with my data migration. Previously I had a Netgear RN104 NAS. It is terrible for 98% of things, but it runs BTRFS natively. This means I've been used to snapshots and all the things here : https://www.synology.com/en-global/dsm/Btrfs So I was a bit staggered when I discovered BTRFS is not entirely available in DSM. As far as I can tell, il should be available in DSM 6. So my questions are : [*]Is there any stable way be to enable BTRFS ? [*]A way that doesn't involve backing everything up and resintalling the machine from scratch ? [*]Any workaround that allows me to use snapshots ? EDIT : I've not updated my bootloader (might be 5.2... Update 3). Is this a problem ? Thanks a lot for your help.
Benoire Posted February 22, 2016 #2 Posted February 22, 2016 1) I think DSM 5.xxx uses an old kernel which had issues with BTRFS so I'd not use it yet, not until 6 is ready. 2) From what I have read with the DSM6 betas, there is no migration tool to move from EXT4 to BTRFS. I think there is a manual method but it was discourged on the synology forums. 3) Can't answer the last question, sorry.
brantje Posted February 22, 2016 #3 Posted February 22, 2016 With DSM 6 we get BTRFS, its only a few months away... Posted via MyXpenology
kouignamann Posted February 22, 2016 Author #4 Posted February 22, 2016 (edited) So my most valid opton would be to wait for DSM 6 on Xpenology machines ? Do you think a valid migration option would be : 1) Upgrade to DSM6 2) Add new disks and create a new BTRFS volume. 3) Copy data from legacy volume (EXT4) to the new BTRFS volume. 4) Erase legacy volume and use it's disks to expand the BTRFS volume I know it's a wild guess since we don't have much info about DSM 6 but I don't have a lot of mileage with DSM.
