Hi Emannuel! What I did (and the only way that worked ) is:
I pointed my iscsi on PVE (Web Interface); Partitioned, Formated (ext4), Created a directory and mounted on /mnt/storage; Added the line "sleep 60 ; mount /dev/sdb1 /mnt/storage"; That was the only way it worked... I'll try the "step B" as mentioned when I have more time!!! Much apreciatted, Leonardo D. ________________________________________ De: pve-user [[email protected]] em nome de [email protected] [[email protected]] Enviado: segunda-feira, 30 de janeiro de 2017 9:00 Para: [email protected] Assunto: pve-user Digest, Vol 106, Issue 27 Send pve-user mailing list submissions to [email protected] To subscribe or unsubscribe via the World Wide Web, visit http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user or, via email, send a message with subject or body 'help' to [email protected] You can reach the person managing the list at [email protected] When replying, please edit your Subject line so it is more specific than "Re: Contents of pve-user digest..."

I have configured my NAS and created a LUN to point my backups, I added it on PVE (it recognized correctly)... Occurs that when I go to Backup\Storage (on web interface) and try to point to the LUN (named as ITRCNAS1) unit it does not appear... If I point to the mounted directory on console it works: /mnt/storage. Is there a way to use the LUN directly? I'm not sure if I can mount a LUN volume on fstab... LUN is already partitioned and formatted as ext4, it's my /dev/sdb1 device. Note: On Web Interface I see the format of that unit is still RAW. Any help is much appreciated, Leonardo D. ------------------------------ Message: 2 Date: Mon, 30 Jan 2017 10:15:32 +0100 From: Miguel González <[email protected]> To: PVE User List <[email protected]> Subject: Re: [PVE-User] software RAID in 4.2 Message-ID: <[email protected]> Content-Type: text/plain; charset=utf-8 On 01/24/17 10:22 AM, Eneko Lacunza wrote: > Hi Miguel, > > El 24/01/17 a las 10:11, Miguel González escribió: >> Reads and in both, Proxmox and therefore in guest VMs. >> >> As you can see in my messages writes seem to be more or less fine around >> 140 MB/s in Proxmox while reads are around 40 MB/s. >> >> At this point I don´t know if there is something related to hardware or >> software, I have raised a ticket with support. > > Ok, I don't think pveperf's "fsyncs/second" is good, it's way too low. > > Also, 42MB/s isn't very good from VM, but maybe qcow2 is expanding the > file there. > > Re-reading your first post I think you have a hw/cabling issue.

I still find fsyncs low from time to time, which I don´t understand, varying from 2-40 is a bit too much variation from my point of view. root@myserver:~# pveperf /vz/ CPU BOGOMIPS: 42667.60 REGEX/SECOND: 1099581 HD SIZE: 1809.50 GB (/dev/mapper/pve-data) BUFFERED READS: 138.73 MB/sec AVERAGE SEEK TIME: 18.94 ms FSYNCS/SECOND: 1.97 DNS EXT: 17.82 ms DNS INT: 13.27 ms (myserver) root@myserver:~# pveperf /vz/ CPU BOGOMIPS: 42667.60 REGEX/SECOND: 1162253 HD SIZE: 1809.50 GB (/dev/mapper/pve-data) BUFFERED READS: 123.24 MB/sec AVERAGE SEEK TIME: 13.28 ms FSYNCS/SECOND: 39.64 DNS EXT: 11.67 ms DNS INT: 19.81 ms (myserver) root@myserver:~# pveperf /vz/ CPU BOGOMIPS: 42667.60 REGEX/SECOND: 1123387 HD SIZE: 1809.50 GB (/dev/mapper/pve-data) BUFFERED READS: 121.61 MB/sec AVERAGE SEEK TIME: 13.83 ms FSYNCS/SECOND: 22.67 DNS EXT: 14.01 ms DNS INT: 13.90 ms (myserver) root@myserver:~# pveperf /vz/ CPU BOGOMIPS: 42667.60 REGEX/SECOND: 1138502 HD SIZE: 1809.50 GB (/dev/mapper/pve-data) BUFFERED READS: 100.28 MB/sec AVERAGE SEEK TIME: 13.74 ms FSYNCS/SECOND: 41.03 DNS EXT: 13.72 ms DNS INT: 12.70 ms (myserver) root@myserver:~# pveperf /vz/ CPU BOGOMIPS: 42667.60 REGEX/SECOND: 1102421 HD SIZE: 1809.50 GB (/dev/mapper/pve-data) BUFFERED READS: 134.41 MB/sec AVERAGE SEEK TIME: 12.74 ms FSYNCS/SECOND: 30.34 DNS EXT: 11.25 ms DNS INT: 14.16 ms (myserver) root@myserver:~# hdparm -tT /dev/sda /dev/sda: Timing cached reads: 16160 MB in 2.00 seconds = 8087.23 MB/sec Timing buffered disk reads: 434 MB in 3.00 seconds = 144.60 MB/sec root@myserver:~# hdparm -tT /dev/sdb /dev/sdb: Timing cached reads: 16492 MB in 2.00 seconds = 8253.77 MB/sec Timing buffered disk reads: 456 MB in 3.01 seconds = 151.44 MB/sec ------------------------------ Message: 3 Date: Mon, 30 Jan 2017 10:44:38 +0100 From: Emmanuel Kasper <[email protected]> To: PVE User List <[email protected]> Subject: Re: [PVE-User] Point my backup to ISCSI Volume Message-ID: <[email protected]> Content-Type: text/plain; charset=utf-8 On 01/29/2017 08:45 PM, Leonardo Dourado wrote: > Hi gents! > > I have configured my NAS and created a LUN to point my backups, I added it on > PVE (it recognized correctly)...

So you have two choice: A) * create a fstab entry for /dev/sdb1 pointing to /mnt/my_mount, mount it * add a directory mount point in PVE for /my_mount ( in gui, add storage -> directory) B) Create an NFS export from your SAN to PVE. As NFS is file based, you will be abled to use the storage directly to put your backups. I advise you B. Iscsi is fine, but to store backup files is not its optimum use case here. ------------------------------ Subject: Digest Footer _______________________________________________ pve-user mailing list [email protected] http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user ------------------------------ End of pve-user Digest, Vol 106, Issue 27 ***************************************** _______________________________________________ pve-user mailing list [email protected] http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
