Bit of an odd one, thought I’d just ask…
So, I’ve 18 identical disks in the JBOD unit.
16 make up the active storage and Parity drive.
only 4 are listed as assigned to the array if I pull up the list of disks (with 12 showing as N/A)
And I seemingly have 3 drives unassigned according to the dashboard…
So, 4 drives assigned to the array, 12 not and 3 spares (out of 2 physical disks)… ???
Weird…
Without knowing more details it’s impossible to say what would be expected and what wouldn’t.
Version of TrueNAS, hardware details and what pools you have/think you have configured would be a start.
Also, not JBOD if you have a parity drive. What is the pool configuration? What version, etc. You basically are saying “I am having a problem” without giving us any meaningful data to help you.
Primarily: Make and model of the JBOD, and how is it connected.
USB and Thunderbolt units are not supported, only proper SAS shelves.
midlct call disk.sync_all -job && service middlewared restart
Does this fix it? Run as root.
Jumping back onto this…
Ok, so the setup I have is a T620 server with 6G HBA expander (Lsi) connected up to a Dataon 1640D 24 slot Jbod.
At the moment, things seem to have sorted themselves out with TNS reporting 2 free drives (2x600gb 15k dell 2.5") and everything seems to be ok.
However, I’m trying to fill the remaining 6 bays and have found 6x1TB 7200 rpm dell drives and (Hooray!) the necessary hotswap sleds/trays to hold them.
Putting one of the disks in however (only one has arrived so far) the system reports that it can see the drive but has a size of 0B as it seems not to be able to determine the disk size. The console seems to scan through the drive and reports
“Read capacity (16) failed”
But all other messages regarding drivers etc state OK.
Trying to get the drive spun up, it just flashes away as if it’s trying to initialise.
any clues? I could power cycle everything but that would be a pain. As I have 3 banks of 8 in the tray I could move 16x600gb to the left and middle sections and then leave the right bank for the 7200rpm 1tb drives, but I’ll have to then lose the two hot spares I have…
Is it a potential formatting issue as the drives are used? if so, is there a way I can identify and scrub the drive from the command line to re-initialise it in some way? I dont mind completely rebuilding the array as I’m not storing any data on it yet until I have all the available slots populated.
Dont want to have to get more 15k drives if I can avoid it as I’m more interested in capacity than speed in this setup.
(its going to be the iscsi storage for my desktop PC once I get the sfp+ cards in at either end and 10G fibre…)
