I'm migrating some VMs from XenServer to PVE. Now, one of these VM, has to be shrinked, if possible, in example, moving from 100GB to about 40GB. Is this possible ?

That's a shame, it is very useful. I've used this kind of export not less than hundreds time, with XenServer (probably, it is the only think I like in that junk software). I can't use ssh because SSH is not directly accessible from outside our network. The only accessible port is the web...

Is this something you plan to add ? It's a very very useful feature. Anyway, i've seen that vzdump is able to send a stream to stdout. Is possible to use vzdump remotely by specifiying the remote host to connect to ? Like "xe -h" in XenServer

I don't want to add an external NFS server. Our backup environment in on a natted network. The ability to dump the whole backup file remotely via API would be better. In example, our current XenServer backup is made by a couple of shell script called from backup server but on the end, they do a...

I've seen that is possible to use the following command line to backup and restore a VM via command line without using a dedicated storage (from the web interface, I'm forced to choose local storage for backup and this is not what i want) vzdump 101 --stdout | pct restore --rootfs 4 300 -...

Sorry for the dumb question but i'm new to proxmox, i'm using it from less than a year and with only 4 VMs currently. How can I export a running VM as a backup image, ready to be restored in case of disaster recovery ?

Anyway what really i don't understand is how to read smartctl output on SAS disks. Official smartctl docs doesn't say much about SCSI devices

Price is not a problem. SAS or SATA are priced about the same for this kind of disk (maybe a couple of euros more) Availability is the real issue. Out sellers doesn't have SAS model in stock and next batch is expected for end of May while SATA are immediatly availability in thousands pieces

Exactly what I've always thought, but this isn't true for error reporting. SATA S.M.A.R.T. is much more details compared to the SAS one, with SAS disks you don't have any attribute to look for but only a generic "Elements in grown defect list" You won't be able to know if disks is starting to...

I'm talking about spinning disks, as wrote, 7.2RPM. If you read specs about HGST 7k6000 you'll see that both SAS and SATA are identical. The only difference is the communication protocol but it's the same mechanical disk. I don't think that all SAS are dual-headed because the SAS disks i'm...

No, is not comparing a SAS 15k vs a SATA 7.2k disks. Most vendor, particularry HGST has both interface for the same mechanical disk. In example, 7K600 series comes with SAS or SATA interfce. It's the same disks, the only difference is the communication protocol. What do you suggest? SAS seems...

Thank you. very interesting read.

Happy birthday. Who is running proxmox in Antarctica? I'm really really curious.

Ok... 3 years then :)

I see, but a test lab is not exactly a production use. I'm looking for real production use in a DC. (something like: we use them from 5 years, not issues at all, or something similiar)

Anyone using Samsung SM863/SM863a SSD from a long time ? Any thought? Currenty, it cost about half an Intel DC S4600, but the Intel has a lower DWPD. The real comparison should be made with Intel DC S3610 but this one is EOL, so is Samsung SM863 a good enterprise drive? Any sudden failures and...

I've migrated one of my XenServer VM made with 4 disks. This resulted in a KVM VM with 4 disks on local-zfs Can I merge these disks into a single, bigger one?

My script doesn't do anything special. It simply skip the extract+merge steps because it does both steps during the VM export. In my case, with XenServer < 7.1 (so, with export speed capped by XenServer to a very low value), exporting a 100GB VM require about 2 hours for the export and 60-90...
