Re: [quadstor-vtl] Failed to start new tape backup session

[QUADStor VTL Support]

Hi,

Please try deleting tapes and bring down the storage pool space
utilization. You should then be able to create tapes with the same label
and work with them.

It looks like the application is trying to write a label at the start of
the tape which should also erase the tape data, but in this case it wont
work because any new writes will fail.

 Hi,

 You need to create enough free space to restart the backups. Right now
 free space still around 1% free (2 TB out of approx 196 TB) which is not
 enough.  You need to bring the free space to more than 10 to 20 TB to not
 have this problem recurring periodically.

Re: [quadstor-vtl] Failed to start new tape backup session

[QUADStor VTL Support]

Hardware compression would reduce storage utilization for new backups. But
the storage pool was already fully utilized. Was storage space cleared
before backups (erasing/deleting a few tapes or adding new storage)

If yes, please send the diagnostic logs

Re: [quadstor-vtl] Failed to start new tape backup session

[QUADStor VTL Support]

Hi,

We had a look at the logs. The out of physical space condition is correct.


*bdev size 128006131548160bdev used 125946502111232*

Around 125TB of the configured 128TB is used. There is some raw capacity
towards the end which we do not use due to performance conditions.



*bdev uncompressed size 125402210316288bdev compressed size 0bdev
compression hits 0*

It looks like all the data is written uncompressed to disk. Please check if
your backup application/job has disabled device/hardware compression.
Compression should bring down the space utilization significantly,





*dedupe size 1845983891456zero size 178126848vcart used 127248372334592*

Of the total 125TB of user data only 1+TB was deduplicated. Which backup
application is writing to the tapes ? What are datasets - File, DB, VMs etc
?
