Proxmox corrupts file system on running VM's when recovery process starts

[koval]

Hello,

My server Dell R 620 Server
Proxmox 5-0.30
Raid 5 PERC H 310
Virtual machines on same server on LVM-Thin
8 VM's is running

I decided to recover from backup one of my VM. After 3 % of done, I found that some of my services on running VM's stopped. I stopped process of recovering my VM and started to check what's going on.
I found that file system on my other running VM's was corrupted. I tried to recover with e2fsck -b command, but unfortunately some files were deleted. Others VM successfully recovered with simple fsck command.

I checked my RAID and nothing special found.

root@pve:~# megacli -pdlist -a0 | grep Error
Media Error Count: 0
Other Error Count: 1
Media Error Count: 0
Other Error Count: 1
Media Error Count: 0
Other Error Count: 1
Media Error Count: 0
Other Error Count: 1
Media Error Count: 0
Other Error Count: 1


SMART is also ok on all disk's.
No strange records on Proxmox Syslog.

What else can I checked ?
Has anyone ever encountered anything like this?

I have details. I think the problem is with Proxmox. When I started to recover my VM's from backup, file system on other running VM's began to corrupt. I checked twice and I saw this very strange behavior. Any ideas ?
