Hello all,

I am newbi to Linux/Proxmox etc but I've used some video tutorials to instal and run Promox on an R710 server. It was working fine for a while now I can't access the webgui but I can SSH into Proxmox and the VMs work. I have tried 3 browsers so I don't think it is the browsers.

VMs running:

TrueNas
Ubuntu Server with Docker/Portainer

The only thing I think has happened is the following -

I used the following video guide:

https://youtu.be/P9gAWrtZsUU

To mount SMB shares from TrueNas in the Ubuntu VM and then direct Portainer to this mount so the containers could use the mounted volume.

In /fstab file the following line was added:

//IP_OF_TRUENAS/SHARE home/username/mnt/Share/ cifs username=USERNAME,password=PASSWORD,rw,iocharset=utf8,noperm 0 0

In SSH on some commands I get input/output error. I'm worried if I reset the server it won't restart and I'll lose data from TrueNas.

If anyone could help it would be greatly appreciated.

Kind regards,

Kozure
 
This is what I get:

Code:
pveproxy status
running

Code:
tail -f /var/log/pveproxy/access.log
-bash: /usr/bin/tail: Input/output error

Code:
netstat -an | grep 8006
-bash: netstat: command not found

Code:
tcpdump -i vmbr0 port 8006
-bash: /usr/sbin/tcpdump: Input/output error

Code:
iptables --list
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

Code:
curl -s -k https://localhost:8006 | grep title
-bash: /usr/bin/curl: Input/output error

Code:
pvesh get nodes
node | status | cpu | level | maxcpu | maxmem | mem | ssl_fingerprint
+======+========+=======+=======+========+===========+===========+=================================================
| pve | online | 2.99% | | 24 | 70.83 GiB | 31.75 GiB |
+------+--------+-------+-------+--------+-----------+-----------+

Code:
pve-firewall status
Status: disabled/running

Code:
uname -r
5.4.106-1-pve

Code:
pveversion -v
-bash: /usr/bin/pveversion: Input/output error

Code:
apt update
-bash: /usr/bin/apt: Input/output error

The Input/output error is usually linked to broken/corrupted disks (from reading on the forum). How can I resolve this?
 
I've gotten I/O errors from having a full volume. lvs and check that your data is not 100%
