Error Traceback provided on the Web-UI

Traceback (most recent call last): File "/opt/rockstor/src/rockstor/rest_framework_custom/generic_view.py", line 41, in _handle_exception yield File "/opt/rockstor/src/rockstor/storageadmin/views/disk.py", line 459, in post return self._update_disk_state() File "/opt/rockstor/eggs/Django-1.8.16-py2.7.egg/django/utils/decorators.py", line 145, in inner return func(*args, **kwargs) File "/opt/rockstor/src/rockstor/storageadmin/views/disk.py", line 322, in _update_disk_state p_info = dev_pool_info[dev_name] KeyError: '/dev/sdal'

I did some more searching and noticed that there appears to be duplicate serial numbers on all of the drives. I believe this could be cause by having both links of the H200E HBA card connected to the MD1200. That is the only thing that I can think of that would cause them to be duplicated.

@Ikyo Thanks for the additional info, you may be onto something with:

And if your hardware arrangement re:

constitutes a multipath arrangement, which I suspect, then Rockstor is, as yet, just not able to recognise such situations. It’s just not multipath aware yet. I hope to move towards this as we progress but we are very much still at the one unique serial per drive as per our Minimum system requirements

But on reading your initial report I had though you were affected by the following bug issue:

which was fixed in Stable release 3.9.2-31 July 2018 via:

which affected with 27 or more drives. But you made no mention of fake serials.

Could you confirm you rockstor package version number via, as root user:

yum info rockstor

As this will help to get started on sorting our what’s going wrong here.

But judging from for example sdat and sdah having, as you say, duplicate serial numbers:

NAME="sdat" MODEL="ST2000NM0001    " SERIAL="5000c50040d4689b" SIZE="1.8T" TRAN="sas" VENDOR="SEAGATE " HCTL="9:0:19:0" TYPE="disk" FSTYPE="btrfs" LABEL="MD1200_2" UUID="d3d69500-5797-4e5b-9a83-74b22dee56a7"
...
NAME="sdah" MODEL="ST2000NM0001    " SERIAL="5000c50040d4689b" SIZE="1.8T" TRAN="sas" VENDOR="SEAGATE " HCTL="9:0:6:0" TYPE="disk" FSTYPE="btrfs" LABEL="MD1200_2" UUID="d3d69500-5797-4e5b-9a83-74b22dee56a7"

I think you have gotten to the bottom on this Rockstor incompatibility. Your presumably multi-path arrangement: i.e. the same hardware drive (by serial) referenced by 2 device names. Could you try removing this hardware configuration and seeing if, post a reboot, all is then well.

Hope this helps and well done on persevering / pursuing this issue thus far.

You are exactly correct about me having it configured for MPIO. I am going to try doing a split configuration and seeing if that helps. I am just not sure if you can daisy change in a split configuration.

@Ikyo OK, that would explain it; hopefully.

I’m afraid I can’t chip in with knowledge re daisy chain as I don’t have any :slight_smile:.

Hopefully others here can chip in with some as it’s just not something I have any experience with, yet at least.

Good luck with the hardware re-config and do let us know how it goes.
