XenServer Local SR: Need another pair of eyes

Kelly

I'm trying to create some new local SRs in XS7 and I'm not getting what I am expecting. Here is my command:

xe sr-create host-uuid=[uuid from xe host-list] content-type=user device-config:device=/dev/sda name-label=”VM Storage" shared=false type=ext

When I run that I just get a
>
and no other response. I end up having to hit Ctrl+C to break out.

Are you trying to use that single sda device or trying to create the SR out of an array?

Kelly

It is a single logical disk built on a hardware RAID 10 array.

Kelly

There are no partitions configured on it either.

DustinB3403

But it shouldn't be /dev/sda that would (if your running from USB) be the USB drive.

A possibility for sure. What does the out put of

ls -l /dev/sd*

show?

Kelly

/dev/sda is the right partition according to fdisk -l

Here is the output of the ls -l

brw-rw---- 1 root disk 8,  0 Jun  7 09:55 /dev/sda
brw-rw---- 1 root disk 8, 16 Jun  6 16:02 /dev/sdb
brw-rw---- 1 root disk 8, 17 Jun  6 16:02 /dev/sdb1
brw-rw---- 1 root disk 8, 18 Jun  6 16:02 /dev/sdb2
brw-rw---- 1 root disk 8, 19 Jun  6 16:02 /dev/sdb3
brw-rw---- 1 root disk 8, 21 Jun  6 16:02 /dev/sdb5
brw-rw---- 1 root disk 8, 22 Jun  6 16:02 /dev/sdb6

This system only has two drives in it?

@Kelly Ok, so sdb is obviously the system drive. Is the RAID controller a Dell/LSI? Might need to get the LSI megaraid-sas or one of their other utilities installed to get us the actual array status. For now, what does

fdisk -l /dev/sda

show?

momurda

what does 'pvdisplay' output?
or 'vgdisplay'

xe sr-create host-uuid=uuidofhost shared=false type=lvm content-type=user device-config:device=/dev/sda1 name-label="blah"

Disk /dev/sda: 24001.4 GB, 24001350991872 bytes, 46877638656 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

No return on either pvdisplay or vgdisplay.

@Kelly So far the drive looks good. This seems silly, be it could be that you'll need to create a partition on the drive for things to work. (Don't ask me why, a raw drive vs a partition shouldn't make much difference.) I'd go with an LVM partition type and use type=lvm like @momurda suggested.

Same response. I just have a > below the command.

travisdh1

@Kelly Well, bother.

xe sr-create host-uuid=uuidofhost shared=false type=lvm content-type=user device-config:device=/dev/sda1 name-label="blah"

Should work. You've stumped me for the day at least.

momurda

Thats weird. pvdisplay/vgdisplay should give you a list of physical devices (pvdisplay) and vgdisplay should show you the logical volumes of your physical disks.

Does the order of the elements after sr-create matter?

It shouldn't, but xe can be a bit of an oddball at times. Could be as simple as a space where one shouldn't be.

Kelly

Ok, so I decided to step through xe sr-create until it stopped complaining. It created the SR with just this:

xe sr-create name-label="VM Storage" type=lvm host-uuid=uuid device-config:device=/dev/sda

I only entered a parameter when it specifically asked for it. I'm wondering if there is an undocumented change in one of the parameters.

Kelly

And the same command worked on the second host in the pool as well (different uuid).
