Unraid 6.1.9 - LSI SAS 9207-8i - Input/Output Error - 48TB (16 x 3TB Drives)

Featured Replies

Hi Everyone,

 

I am a new purchaser of unraid and recently setup my beefy rig with unraid.

 

My machine specs are below

 

* Norco 4RU 24 Bay Case

* Supermicro Motherboard - Model X9DR3/i-F

* 2x Intel Xeon E5-2670 Processors

* 2x LSI 9207-8i Host Bus Adapters (to pass disks through to unraid)

* 16 x 3TB Hitachi Enterprise SAS Drives on LSI Cards - 4x rows of 4 in case with 2 disk rows per controller port ( 2 ports per controller)

* 4x 1TB Samsung 850 Pro 1TB Drives on board SATA Controller in AHCI mode

* 96GB DDR3 ECC Ram

 

The problem I am having is any drive that is on the LSI cards even being passed through is actually giving me input/output error

when attempting to fdisk access the drive.

 

The LSI Cards are running IT Firmware 19 which is the correct firmware to run for these cards.

 

I do not get this same problem if i boot up with ubuntu or centos and try access the disks only unraid.

 

I have attached the log for your review and comment and would appreciate any input you have in helping me nail this one.

 

Thanks

Shaun

to pass disks through to unraid

 

Does this mean you are trying to run unRAID in a VM? It isn't officially supported but some people claim success.

Oh no definitely not - this is bare metal.

 

I am saying that my UnRaid 6.1.9 can see the disks but wont add them as usable, or turn blue.

 

I started working through the reasons why when i found that for each of the disks connected to the LSI 9207-8I

Host Bus Adapter or Pass Through Controller would not actually be able to read the disks and when i try i get

the input / output error as shown below

 

root@snowbox:~# fdisk /dev/sdh

Welcome to fdisk (util-linux 2.21.2).

 

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.

 

fdisk: unable to read /dev/sdh: Input/output error

 

Really looking to see if anyone can offer some advice as to why this occurs only in unraid os.

 

Thanks

Shaun

 

 

Your syslog has many error messages like this:

 

Aug 17 01:03:13 snowbox kernel: blk_update_request: I/O error, dev sde, sector 0

Aug 17 01:03:13 snowbox kernel: Buffer I/O error on dev sde, logical block 0, async page read

 

Several disks are affected, including /dev/sdh that you use in your example.

 

Messages such as this

 

Aug 17 01:03:13 snowbox kernel: mpt2sas1: log_info(0x3112043b): originator(PL), code(0x12), sub_code(0x043b)

 

appear over and over again. I don't know what it means, other than it's a SCSI message.

 

Is the 9702 fully supported? I don't know. A quick search for it in the context of unRAID revealed nothing. Did you check for compatibility yourself before purchasing the hardware?

 

Post your diagnostics zip.

Hi John,

 

I am actually a server hosting company the hardware we had laying around that we were going to use for other purposes.

 

Not bad to have this quality hardware laying around though :)

 

I have actually replicated the error now on Ubuntu 16.04 - so believe this not to be an unraid only issue now.

 

Last night Ubuntu 14.04 could read the disks fine - so am working through what the issue is as it maybe driver related.

 

The LSI 9207-8i is natively supported in Linux and is one of the most popular used LSI cards on the market besides the previous model.

 

All distributions natively support and have drivers for it - for 2+ years, so assumed that Unraid is no different which is why i reached out for help.

 

Will update this thread to my findings.

 

Thanks

Shaun

Wow ... what a headache.

 

The solution was to boot up a Windows 10 CD - run repair and clean all the drive partitions.

 

I wanted to respond so that others new how to fix this issue should they come into it themselves.

 

The drives were recycled - not new but every single drive would provide that result.

Thanks for the update, it really helps the community when others post their findings and fixes,

 

So do you now have an operational unRaid system? if so, Welcome then, water is cool and the beer cooler is floating somewhere.  :)
