Replaced drive, inconsistent device names

[budmannxx]

I had to replace a drive in my pool, and everything went smoothly. I think I must have mistyped a command somewhere, however, because the new drive is listed as "ada0" while the other 5 drives are "gpt/ada#". The pool is healthy and seems to be operating normally. Can anyone confirm if this discrepancy matters at all? I'm on FreeNAS-8.0.4-RELEASE-x64 (10351).

Code:

# zpool status
  pool: freenas
 state: ONLINE
 scrub: none requested
config:

        NAME          STATE     READ WRITE CKSUM
        freenas       ONLINE       0     0     0
          raidz2      ONLINE       0     0     0
            ada0      ONLINE       0     0     0
            gpt/ada1  ONLINE       0     0     0
            gpt/ada2  ONLINE       0     0     0
            gpt/ada3  ONLINE       0     0     0
            gpt/ada4  ONLINE       0     0     0
            gpt/ada5  ONLINE       0     0     0

errors: No known data errors

Camcontrol shows all the devices:

Code:

# camcontrol devlist

<SAMSUNG HD204UI 1AQ10001>         at scbus7 target 0 lun 0 (ada1,pass1)

<ADATA USB Flash Drive 0.00>       at scbus13 target 0 lun 0 (da0,pass6)

But gpart show only has 5 of the 6 HDDs:

There was a ticket just opened on this problem and it was closed as "won't fix" because it's supposed to be fixed in 8.2....

 

[budmannxx]

Got it, thanks. Just to be clear though, is this going to cause any problems while I'm still on 8.0.4? Will I need to do anything special when I upgrade to 8.2?

 

[ProtoSD]

In your case you will be fine, the other guy can't even replace his drive with using the command line.

You won't need to do anything special to upgrade to 8.2, but the naming of your disks might stay the way they're now.

 

[budmannxx]

OK, great, thank you. Got scared there for a minute. Please ignore my last PM--sorry to hit you from 2 angles on this.

Hi Bud, how do you copy text from your console? Or is there some way to get the the console over the GUI?

I SSH into my FreeNAS box from Windows using PuTTY. Simple copy/paste from there.

 

[anudureio]

I have exactly the same issue... http://forums.freenas.org/showthrea...ive-but-now-doesn-t-have-GPTID-label-anymore-

@protosd; is there any way to fix the drive name from adaX to either GPT or GPTID if we'd like to have it all harmonious again?

many thanks

Sorry to bring this old thread back online but its the most relevant I can find. I'm having this exact same problem, replaced a faulty drive and now it lists it as ada3 rather than gpti.

Any ideas?

Give up on FreeNAS, I then tried NAS4Free for a while then had odd issues with mounting. BSD is just too problematic. Went for a Asustor, fan-freaking-tastic, 12 months now plug and pay. Given the hours and hours I wasted trying to sort HDD naming and mounting issues with BSD. Life wasted, lesson learnt, commercial solutions are now cheap and well designed.

Yeah, you replaced it from the CLI(you bad boy) and not the WebGUI(like you are supposed to). Use the manual! You should replace it from the GUI so that the problem is fixed...

Why does freenas use partitions for zfs pools instead of the entire disk as is recommended by Oracle?
Is there a specific advantage do slicing the disk, allocating 2GB /disk to swap and using the rest as the pool? Isn't this more risky then having zfs control the entire disk (as is recommended)?

Per Oracle:

http://docs.oracle.com/cd/E23823_01/html/819-5461/gcfog.html

The recommended mode of operation is to use an entire disk, in which case the disk does not require special formatting. ZFS formats the disk using an EFI label to contain a single, large slice.
