Disks gone after DSM update


Recommended Posts

Hi. Today I have updated to XPEnoboot 5.2-5644.5 and after that I made server update to newest release DSM_5.2-5644 Update-5 ( from update 3). After reboot all my shared volumes were lost. I checked which disks are visible and there is only 1 volume (2 hdds in raid) connected directly to mainboard / all other 6 hdds are connected by LSI SAS2008 sata controller.

Could You please help me to make it work again :sad: ?

you can 'downgrade' XPE by using the earlier boot image, 5644.4. Try that and see what happens

downgrading DSM updates is harder. You could try;

disconnecting your drives

a new install of base DSM 5644 on a spare drive, connected to mobo sata port 0, create a volume and then delete it.

reconnect other drives and boot up

If you are lucky then DSM will boot from drive 1/sata 0 with the base DSM and you should see your other drives/volumes (system partitions may be corrupted but you can repair that)
