Do you not have backups already?
Anyway, My motto is always give yourself a way out.
We cannot tell you where to put the backup, because we do not know what you have. If you have another linux machine, just rsync it.
Or a usb drive.
1. Backup to a usb drive
2. Shutdown the vms and do...
I am busy re-reading all these great reply's for the 3rd time. And will read them again after that to be sure I've got it. To those replying here, I felt a need to post a very heartfelt THANK YOU!
I really mean it. Thank you so much!
Oh, I guess I do have one question already, if I do just one...
FYI
4 re4 enterprise drives 7200 rpm
proxmox 4
raid 10 zfs
1 128 gig samsung pro ssd for larc (Have no idea what difference this makes)
Inside a vm, here are my results.
hdparm -tT /dev/vdb
/dev/vdb:
Timing cached reads: 20098 MB in 2.00 seconds = 10058.33 MB/sec
Timing buffered disk...
For a small budget.
This is for a single host.
I've been greatly disappointed in ZFS raid 10, the FSYNCS/SECOND doesn't get it. at all!
Proxmox existing vm with mdadm raid 1 = 999 beats the crap out of it. (Tested while guest were running, one of them a mail server)
old perc5 raid card=...
hmm, am a bit confused then, the proxmox installer created the raid 10, but two drives have a boot partition like this
/dev/sda1 34 2047 2014 1007K BIOS boot
/dev/sda2 2048 3907012749 3907010702 1.8T Solaris /usr & Apple ZFS
/dev/sda9 3907012750 3907029134...
proxmox 4 plan for drive failure zfs raid 10
Ok, I get the zfs commands for replacing a drive. However, during testing, I yanked out a drive:
did zpool online sda2
zpool rpool scrub
However, the sda2 caught my eye..
Upon running fdisk, I notice two of the drives have a boot partition.
on the...
Am testing a server, and get this in the logs. On my other proxmox 4 server, I do NOT get these in the logs..
Is there an issue I should worry about?
audit: type=1400 audit(1447232527.712:2): apparmor="STATUS" operation="profile_load" profile="unconfined" name="lxc-container-default" pid=1355...
The new 4.0 beta no longers seems to work with usbmount, through no fault of it's own. The package is no longer maintained. So I reverted to mounting by drive label.
mount -L backup_drive /mnt/backup_drive
One more time for the sake of completeness. One of the vm's was still slower than all getout. Windows 2012R2.
I removed the virtio driver and went with the e1000. Fixed, done. The world is a better place now.. :)
Have no idea what was up with that or why the upgrade affected it.
Thanks mir,
For completeness, here's what I did. I had to blacklist the original drivers.
apt-get install pve-headers-$(uname -r) build-essential dkms ethtool
wget wget http://ftp.datanom.net/pve/r8168-dkms_8.037.00_all.deb
dpkg -i r8168-dkms_8.037.00_all.deb
echo "blacklist r8169" | tee -a...
Thank you so much!
I've some intel nics being overnighted. :)
However, I'd like to try this. 2 more questions, if you don't mind.
1st Shall we assume I cannot do this remotely?
2nd What might I do if I need to "roll this back?"
Wouldn't ask, but we're live out in the sticks and I do not...
On a file server I plan to move to proxmox, I've a question about the file server storage format.
I plan to put the operating system on qcow2
However, the 300 gig disk for the files (will be on the same server), I was wondering if that shouldn't be raw format?
Sound about right? A 300 gig...
This sounds good. Of course they need to know the backup was successful, so I guess I might point the email to them. (Though I'd like to get a copy)
Then just have them swap the drives after they get the email which would mean the backup had finished...
Having used proxmox for our own needs, I'm thinking to use it for some small clients.
I need some ideas for simple (very simple) instructions to check the backup and swap usb drives:
Have you guys got a method you tell a secretary or whomever to change backup drives?
