ERROR (CHKAVRUM) and ERROR (MKROOM01)

Hello,

I use the version xsibackup-pro 1.0.0.

so far so good.

The backup seems to be running normally, but the following error will always be displayed in the report:


XSIBACKUP-PRO 11.0.0 AT HOST:
VMware ESXi 6.5.0 build-7388607
--------------------------------------------------------------------------------------------------------------------
Done cold backup (id: vmmst) using onediff (no compression)

• [ Thu May 24 21:01:04 UTC 2018 ] ERROR (MKROOM01), details Error: cannot make 0G of room, only 0G can be made available
---------------------------------------------------------------------------------------------------------------------


The backup is created clean. Apparently, the query of the disk space does not work properly.

there is definitely enough space on the backup medium.
On another host with the esxi-version 6.0 everything works correctly.

Has this problem already had someone else or is there already a solution for it?

best thanks and best regards

Re: ERROR (CHKAVRUM) and ERROR (MKROOM01)

I guess you mean you are using v. 11.0.0 ("I use the version xsibackup-pro 1.0.0.")

Some user that contacted support lately had a similar issue, it was a hardware problem. That doesn't mean yours is something similar, but most likely in these cases.

Run this command:

df -h /vmfs/volumes/nfs-shares/vmware-vm/xsi-backups/dusesxisrv02

And see what is the output.

In your case your path is very deep too: /vmfs/volumes/nfs-shares/vmware-vm/xsi-backups/dusesxisrv02
Try something closer to the NAS root just to make sure it's not the path depth.

NOTE: and do not forget that XSIBACKUP-PRO 11.0.0 RC2 is a Release Candidate that should not be used in production. We'll release a final version in some days.

Re: ERROR (CHKAVRUM) and ERROR (MKROOM01)

Here is the output of the df -h command:

----------------------------------------------------------------------------------------------------------
[root@dusesxisrv02:~] vmware -vl
VMware ESXi 6.5.0 build-7388607
VMware ESXi 6.5.0 Update 1

[root@dusesxisrv02:~] df -h /vmfs/volumes/nfs-shares/vmware-vm/xsi-backups/dusesxisrv02
Error when running esxcli, return status was: 1
Errors:
Cannot open volume:
----------------------------------------------------------------------------------------------------------

and here's the output of the df -h command with a shorter path:

----------------------------------------------------------------------------------------------------------
[root@dusesxisrv02:~] df -h /vmfs/volumes
Error when running esxcli, return status was: 1
Errors:
Cannot open volume:
----------------------------------------------------------------------------------------------------------

It looks like the command dm on ESXI 6.5 is not working or not supported.
The same command, even with the long path, works fine on an ESXI 6.0 host.

Look here:
----------------------------------------------------------------------------------------------------------
[root@dusesxisrv01:~] vmware -vl
VMware ESXi 6.0.0 build-6921384
VMware ESXi 6.0.0 Update 3

----------------------------------------------------------------------------------------------------------
Is there a way the to install the "df" command under esxi 6.5?

Or is there an alternative command for "df"?

Thanks and best regards

Re: ERROR (CHKAVRUM) and ERROR (MKROOM01)

The df command is indeed present in ESXi 6.5.0
In fact nothing in your output is telling you about its absence

[root@dusesxisrv02:~] df -h /vmfs/volumes
Error when running esxcli, return status was: 1
Errors:
Cannot open volume:

df -h command runs, but it's returning an error. You have some big problem with your datastores setup or your ESXi is plainly broken.

There is other possibility. If you are using one of those evil manufaturer custom distributions, you must know they contain arbitrary modifications, made in sake of the manufacturer commercial interests, and not yours sad, and thus cannot be considered to be ESXi.

If the latter is your case, switch to an official ESXi build ASAP.

Re: ERROR (CHKAVRUM) and ERROR (MKROOM01)

Ok, thanks for your quick response. I will now check my system again to limit the error or find them.
If necessary, I will reinstall the host system.

Best regards
