@Tristis-Oris thanks , I missed a file
I pushed it just now

florent

@Tristis-Oris that is already a good news.

I pushed an additional fix : the NBD info was not shown on the UI

florent

Could you retry nbd + target a block based directory ?
ON my test setup, with the latest changes I get better speed than master ( 190MB/s per disk vs 130-170 depending on the run and settings on master)

I got quite a huge variation between the same runs (40MB/s)

@vmpr the oldest one is always a full
a delta is the difference between this backup and the previous, thus we need

You could do infinite delta, without making full, but this comes with a risk : if anything goes wrong ( on backup or storage) , you'll lose the full backup chain

Would it be possible to store a shorter chain here , and use a mirror backup to do longer retention on a cheaper storage ?

florent

@Tristis-Oris I made a little change, can you update (like the last time ) and retest ?

florent

@Tristis-Oris Do you have the same performance without NBD ?
Does your storage use blocks ?

florent

@Tristis-Oris ouch that is quite costly
Can you describe which backup you run ?
Can you check if the duration is different (maybe this is a measurement error and not a slow speed) ?

florent

ih @Tristis-Oris and @Davidj-0 I pushed an update to better handle NBD error, please keep us informed

@nodje said in Create a VM with an existing iSCSI disk:

Is there anyway to achieve an iSCSI mount without automatic LVM VG creation?

You can try with the "RawISCSISR" driver but it's not really tested on our side, I can't confirm that it will work. It doesn't support creation of VDIs but you can use it to access existing LUNs on a target.
