Can't add drive after sucessful pre-clear, entire array won't come online

Featured Replies

I've successfully per-cleared a WD 2TB EARS (unjumpered), stopped the array, assigned it to slot 5 (sde). As expected, the server tells me that a new disk was found, I click the box that "I'm sure I want to do this" (add to array), and then hit START.

Nothing happens thereafter though, even after a few more refreshes and a few more attempts. None of the disks actually come online, and I have no clue as to why. I haven't even gotten as far as seeing the "Format" button.

 

I'm attaching a syslog, and I'm also copying also the results from the pre-clear below. Not sure if rebooting the server would help, or anything...

Anyone have any insight into this? It'd be much appreciated. Thanks!

 

PS I had posted this in reply to another thread, and lionelhutz pointed out I'm getting errors on sde, which is the new drive in question.

I'm also attaching a screenshot of the state I seem to be stuck in, for what it's worth.

Looks like it cannot write to /dev/sde (the new disk) to create the MBR on it.

 

 

can you type the following and see what the partitioning looks like?

 

fdisk -l -u /dev/sde

Something is very odd with you system.

First it is not the complete syslog, but perhaps only the last 1000 lines.

 

Second, you precleared WD20EARS but "sde" from the partial syslog with a lots of errors is your old Seagate 1.5TB. You are sure that they are no cabling errors (it can happens to everyone).

@Joe L.,

I typed it via telnet, and nothing happens.

 

@bcbgboy13,

I'm attaching the entire syslog here now, I thought I'd only include what I thought was the relevant bits...

Hm, weird, the whole thing with the Seagate (which, afaik, should be on sbd).

 

Well you never know, maybe some cables did come loose - should I power down, you think, and check the connections, and reboot?

Alright, so the culprit was indeed a SATA cable that was ever so slightly off-axis - sometimes, it really is that simple.  ;) Funny though that it pre-cleared with no problems, because I didn't touch it since. Weird.

Your mention of my (sdd) Seagate drive, what with the erros and such, could you take a quick peek at my new syslog to see if the matter is remedied?

@Joe, here's the result of what you asked:

 

  Device Boot      Start        End      Blocks  Id  System

/dev/sde1              64  3907029167  1953514552  83  Linux

Partition 1 does not end on cylinder boundary.

 

Thanks for your help!

No further comments now from me now - I am passing the ball to Joe L.
