I'm only running this on my home network. wink

Here's what I did so far:

  • Cleared /tmp and /scratch/XSI/XSIBackup-DC/tmp

  • Used fresh folders and my original folder

  • Tried automatic and manual GUI backups and a combination of both

  • Tried both 10M and 20M block size

It has passed all the tests using 1.4.3.0!

So either something screwed up originally not clearing /tmp? Or something is happening at that time that is causing it. The only thing I've found is a cPanel host on a different network is backing up at a similar time (you don't get the exact time, but I'm confident there is an overlap). Is there anything that would cause a segmentation fault on a slow speed disk? It's a QNAP NAS, connected by NFS to ESXi.

There's loads of space on the target volume!

Ok, what I tried is --block-size="10M" but using a fresh folder and run automatically only... and it worked!

So I set up --rotate="2" and a cron that backed up every hour for 3 hours and it backed up and pruned the backup fine. big_smile

I'll try 20M again, but this time I'll try doing it in a fresh folder and run automatically only...

Right, I upgraded to version 1.4.3.0 and ran it manually from the GUI just to check and it ran fine. Then last night was the first time it ran automatically and it gave a segmentation fault:

Its running ESXi 7.0 Update 1

you should upgrade to 1.4.3.0 that will fix it, if the problem was due to lack of resources

Thank you. I'll let you know how I get on.

#5 Re: General matters » VMWare ESXi: hardware Segmentation fault » 2021-01-11 13:50:02

I am getting a segmentation fault too. I'm running version 1.4.2.7. It was always 2 or 3 weeks since working fine and then segmentation fault.


xsibackup.log using --block-size=1M

-----------------------------------------------------------------------------------------------------------
--rotate option was detected, retrieving backups to prune...
-----------------------------------------------------------------------------------------------------------
ROTATION: set to 28 days
-----------------------------------------------------------------------------------------------------------
No backups to prune per day offset
-----------------------------------------------------------------------------------------------------------
Removed <tmp> dir OK
-----------------------------------------------------------------------------------------------------------
Unlocked backup OK
-----------------------------------------------------------------------------------------------------------
Segmentation fault


Then when I increased the block size to --block-size=20M it worked (from the GUI) and then it failed the first auto backup due to this:

error.log

-----------------------------------------------------------------------------------------------------------

-----------------------------------------------------------------------------------------------------------
SIGTERM (11) condition was trapped: check logs for more details

Which is weird because I have loads of spare space! So I tried running it manually again (I didn't touch anything else) using the GUI and it worked fine! The backup job is 5 VMs, 400GB.

Hi,

When I try the --install-cron option I don't get the installing cron question, I get:

Hi,

Where abouts can I send the file? I only see a text box on your main site.

Alex

UPDATE FROM ADMIN 2018-04-23 09:00:

We sent you an e-mail to your registered e-mail address, but the message bounced with a domain not found error.
Please, write to us through our webform: https://33hops.com/formulario-de-contacto.asp
It does not matter if it does not allow you to upload files, we'll reach you back from a regular e-mail address.

UPDATE FROM ADMIN 2018-04-23 09:46:

There is a small inconsistency in your log, which is: your VM name is WHM (in capital letters), while the directory where the files are stored seems to be lower case /vmfs/volumes/datastore1/whm/whm_0.vmdk. XSIBackup can handle this without issues, as it will look for the name of the disks in the .vmx file, but I would consider checking the VM structure, as it seems to have been renamed manually. That file is the key to know the cause of your issue, so please, send it to us to delve into your issue.

UPDATE FROM ADMIN 2018-04-23 09:57:

We keep on getting this error when writing to you:

Please provide an alternative e-mail address (gmail.com, yahoo.com or similar would be the best)

I had an error this morning... it has been working great but at 0500 this morning I got an error in my email saying:

ERROR CLVMKFS1 details: [WHM] error: vmkfstools error details: Failed to clone disk: Not a directory (1310729).

It left a weird file in the /vmfs/volumes/QNAP/VMware (my NAS datastore) folder. Instead of there being a folder called "WHM" (my server name) it left a file "WHM" just 9kb big.

It then went to backup the remaining servers just fine, in folders. I tried running it from the command line and the backup completed fine. Any idea what caused this?
