DELL R710 + PERC H730 + 6x 8TB HUH728080AL4200 - no go for Xenserver?


Bartosz Maciejewski

Question

Hello,

 

Despite trying everything I guess even with trying reformat for 512e from knoppix live cd and sg tools with help of this post (https://homerl.github.io/2016/08/10/Advance-reformat-4Kn-HDD-to-512-Bytes/)I am unable  to use XenServer with this configuration because i of disks that has 4kn logical blocks. I can't change block size neither in PERC controller or from linux and sg tools. 

 

XenServer installs just fine on one huge 32TB RAID 5, but then i can't create any disk or install any update.

 

Tried XenServer from 7.2 to 8.0 - same result (see the screenshot).

This controller should be supported by any of this release - https://citrixready.citrix.com/dell-inc/dell-perc-h730.html

 

Is there any other option than waiting maybe for next release with support of this disks/configuration?

Yep, so far 512e and 4k aren't supported. You need old fashioned drives instead of new fancy drives.

But I do have a thought. Try this. Create a rule in /etc/udev/rules.d and call it something like 

71-block-max-sectors.rules

 

For the contents of the new rule do this:

 

ACTION=="add|change", SUBSYSTEM=="block", RUN+="/bin/sh -c ' /bin/echo 512 > sys%p/queue/max_sectors_kb'"

 

Restart the server and see if that makes a difference.

Unfortunately, after what Alan proposed notjing changed in creation of disk. Same error as before - SR_BACKEND_FAILURE_78.

512e drives are supported.

 

4kn drives will work but not with the default LVM local storage. If you create the local storage as ext, either by selecting the install time option (something like optimise for XenDesktop) or by deleting and recreating the LocalStorage through the xe CLI tool then it should work.

Bad luck, still can't get it working with ext4, or am I doing something wrong?

What I ended up doing is creating 3x 7,3TB RAID 1, instead of 1x 34TB RAID 5 in PERC. When installing I choose Virtual Desktop optymization, but none storage appeared in both XenCenter and xe sr-list. I can't add it from CLI also.

 

What bothers me is, even when doing clean install all disks are LVMs instead of EXT.

The SR operation cannot be performed because a device underlying the SR is in use by the host.

If you want ext3 instead of LVM, you have to choose the option to set up for IntelliCache, which makes them ext3, even if you opt not to use IntelliCache. But this should be covered by the thin provisioning option (which I think was reworded since XS 7.X). Perhaps there's an upper size limit on the volume? Or perhaps a concatenation issue? I'm not really sure.

 

Interesting about 512e support - I take it this is new for CH 8.0?

Tobias, is there any other option except checking "Enable thin proviosioning" (see my screenshot in last post) to enable IntelliCache thus making SR ext?

I do not believe so. You can of course create an ext-based SR from the CLI.  The syntax is something like:

 

xe sr-create device-config:device=/dev/sdd1 name-label="New Local Storage" shared=false type=ext

 

You have to of course set up your device and make sure it's properly configured, partitioned, etc. first.
