@scottalanmiller said in XenServer installation SR issue:
The RAID array should appear as a single drive and nothing that XS does should make a rebuild of the array needed. If that is happening, there is a deeper problem.
It does. It shows as a single 6 TB "drive"
Should not need to rebuild, then. If the underlying array is corrupting, then the issue is at the controller or disk level.
Any recommendations on what to check next on the controller and disks?
Most likely thing there is memory issues on the controller cache. See if you can get a diagnostic from Dell.
I wonder if the battery on the controller could be screwing with that. The other day, there was a message stating "W1228 Raid controller battery capacity < 24hr" It was gone the last time I checked this morning.
It's worth replacing if the system is sending alarms about it.

Should only be a problem if your power is not solid.

I'll run the built in LifeCycle diagnostics when I get home to see if it finds anything.

XS is actually installed on this array. If the RAID controller was corrupting the array, wouldn't this hose the XS installation as well and not make it bootable?

Most likely, but not definitely.

@fuznutz04
What does lvscan show you?
I had a similar error once because my lv was not active.

I'll check when I get back home tonight. Thanks.

If XS is installed on the array, you should not be running 'fsck /dev/sda'
What's the output of
parted -l /dev/sda -
@travisdh1
So here is what that command returns:[root@xenserver ~]# parted -l /dev/sda Model: DELL PERC H700 (scsi) Disk /dev/sda: 6000GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: pmbr_boot Number Start End Size File system Name Flags 5 1049kB 4296MB 4295MB ext3 2 4296MB 23.6GB 19.3GB 1 23.6GB 43.0GB 19.3GB ext3 4 43.0GB 43.5GB 537MB bios_grub, legacy_boot 6 43.5GB 44.6GB 1074MB linux-swap(v1) 3 44.6GB 6000GB 5956GB lvm Error: ff8e3b--dd7c--c3c4--3125--22569f5bbd77-0bff8e3b--dd7c--c3c4--3125--22569f5bbd77: unrecognised disk label Model: Linux device-mapper (linear) (dm) Disk /dev/mapper/XSLocalEXT--0bff8e3b--dd7c--c3c4--3125--22569f5bbd77-0bff8e3b--dd7c--c3c4--3125--22569f5bbd77: 5955GB Sector size (logical/physical): 512B/512B Partition Table: unknown Disk Flags: -

@fuznutz04 @BRRABill may be correct, that lv isn't getting loaded for some reason. Does 'lvscan' show anything?
The 'unrecognised disk label' shouldn't happen. Something went wrong for XS to not load lvm on boot, figuring out what is the hard part. If it's the same thing that happened before, @scottalanmiller is probably correct that the RAID card is at fault.
-
@travisdh1 I just did a test on the card using the built in diagnostics with the LifeCycle controller. All tests passed.
The hard drives in the RAID set were taken from another old NAS device that had it's own RAID on it. Could something be left over on the disks that is not being properly wiped during creation of the new RAID set?
-
New plan. I'm going to destroy the entire RAID array again, and recreate. This time, I'm going to do a full initialization. Previously, I just did a "fast initialization." with 4 3 TB drives, this should take about 1.5 years to complete.

At least it's RAID10, so only 1.5 years instead of 6 years for a RAID6

Valid point. Glass is half full.

It does say it is ACTIVE though, which is strange.
But it definitely seems like XS isn't "formatting" it correctly. "Formatting" being whatever you call setting a LV up.

LV would be voluming. Formatting is a reference to the file system level.

Thank you LVM/Linux sensei.

48% initialized. I might actually be able to try an install again today!

Are you watching it? It always goes slower that way.
I like to go across the building and have a few beers while waiting.
