Backup keep failing

@olivierlambert @nraynaud are you able to assist please?

@fred974 Hello Fred, I'm working on removing the timeout error, in the mean time you can remove it by increasing node memory by at least 2Gb.
You can not stop the coalesce from happening, the only thing that can be done is planning the backup at a different time.
I don't know what to do of the VDI_IO_ERROR.
Nicolas.

coalesce
Hi,
I have now removed all the backup jobs from XO and a few hours later, I can still see the same coalesce screen above.
My understanding is that they meant to clear after a while

@fred974 Could anyone please assist me in resolving this Job canceled to protect the VDI chain error ?

Protecting the VDI chain is not an error, but… a protection.

Hi,
Its a protection from what? How do I resolve this issue?
I am unable to perform any backup at all -
Have you looked at the link given when it's happening? This link will send you to our documentation.
Everything is explained here: https://xen-orchestra.com/docs/backup_troubleshooting.html#vdi-chain-protection
A good reflex is to always have the documentation near you, there's a search bar also. Really, it's the first step you might do always before.
-
@olivierlambert I have read it but struggled with some of the English (my problem). I'll try to read it again.
My SR was almost full so I guess it couldn't run it to protect to get any bigger. I am moving VM away to free some space and see if this fix it -
Not enough space means not enough space to coalesce, and therefore XO will prevent to continue and fill entirely your storage because of uncoalesced chains.
