Hi, sorry i am not frustrated about proxmox. I am frustrated about the situation. Sorry if i didn´t write it clear. I have now remove access to the openfile box and will do some tests tonight.

Ok. createt a new partition on the TheCus Storage with blocksize of 4096. Now the Login/Logoff messages on the I4500r comes again an the I/O errors on Kernel log on the Proxmox Server. proxmox02:~# vzdump --snapshot --compress 9999 INFO: starting new backup job: vzdump --snapshot --compress...

i can´t test openfiler at the moment because i am on holiday. I didnt have access from here to the openfiler box only to the TheCus Storage. The i/o errors comes only, if i make a vzdump from an kvm on the TheCus Storage AND! the blocksize is greater than 512. The there are many login/logoff...

at the moment not with blocksize of 512. With blocksize greater than 512, i have get I/O errors.

Think, this is a problem of the blocksize and qmigrate can´t handle it. Can this be? I can create a second volume on the thecus with blocksize of 4096, if you want. If i have a volume with a blocksize greater than 512, all KVMs on this partition works fine. Only vzdump and qmigrate makes trouble.

Ok, with new formated iscsi storage and a block size of 512, the backup in snapshot mode works fine now!

I have done 3 tests.. 1. Ping the machine ... didn response if the backup starts an the snapshot creates. Machine answer if the snapshot is done 2. There are 10 serial ports, that become every second data from subsystems. The ports becomes errors / timeouts if the snapshot will create 3. VNC...

I have tested it with our TheCus I4500r. There you can setup the blocksize for the iscsi volume. At this time, i dont have access to the openfiler box. I am this week on holiday. Regards, Valle

The Logfile looks normal for me Oct 17 16:32:02 INFO: Starting Backup of VM 112 (qemu) Oct 17 16:32:02 INFO: running Oct 17 16:32:02 INFO: status = running Oct 17 16:32:02 INFO: backup mode: snapshot Oct 17 16:32:02 INFO: bandwidth limit: 10240 KB/s Oct 17 16:32:04 INFO: Logical volume...

Hello, now my backup problems are solved, new problems arrived. I have 2 time critical kvm machines running. If i make a backup with vzdump --snapshot the machine will freeze for 300 seconds. In this time, cirital data will become a time out. How can i reach, that there is no timeout if the...

or in /var/lib/images for kvm based machines.

Ok, now i have formated the base storage with a block size of 512 on the iscsi storage and the backup with vzdump works, too! After a few test more, i found that only a block size of 512 works. All block size bigger than 512 will not work with vzdump backup. qmrestore works with a blocksize...

Hi, you must change the VMID directory names. As example if you change from 99 to 100 you muste change the dirctory Name from 99 to 100, too for the machine! Regards, Valle

i have tried it with all 3 discs above. All are the same problem. I have deleted the lvm on the iscsi for more tests. The iscsi store is empty now. i think it is the block size from 4096 on the iscsi store that are make the problem.

so, i have checked the vzdump function with the iscsi storage again. If i use vzdump the backup from the iscsi storage never finished. Look at topic on the top. Today i make ab backup from the iscsi storage with proxmox01:/var/lib/vz/dump# dd if=/dev/pve-kvm/vm-111-disk-1...

ok, have setup a nfs server with unfs3 in debian (32bit) and it works now. The only thing is the iscsi storage, i cant make a backup the iscsi storage to nfs server *grrrrrrrrrrrrrrr*

ok, i will ask there.

Hi, its the latest OpenFiler 2.3 (32Bit) with NFS v3 Support directly installed on a PowerEdge850. I have read bevor, that NFS only support filesize that not greater than 2GB. The Wiki says: support for 64-bit file sizes and offsets, to handle files larger than 2 gigabytes (GB); But i have a...

ok, today i setup a nfs server. The server runs only under a 32bit environment. Is there a wait, to split the backups that are bigger than 2GB? Because of the limit of 2GB files, the nfs backup ended with errors. Oct 15 18:01:03 INFO: status = stopped Oct 15 18:01:03 INFO: backup mode: stop...

proxmox team are the best ;-) Thanx and a good weekend....
