How to manually copy containers to another Node in a cluster?

[Saroop P V]

I have a cluster with 3 nodes. Each node has 2 drives. first 2TB HDD and a second 500GB SSD. Proxmox installed on 2TB and LXC containers on SSD. Rebooted one node today since then containers don't start.

Backup or Migrate failed due to bad sectors on SSD.
How to manually copy the containers to another Node?

Hi,

Bad sectors can not be solved by anything. How can you copy the data from a bad sector (=unredable)?

 

[oguz]

hi,

you can try using 'ddrescue' or other data recovery tools to copy over the functioning sectors from the disk. depending on how bad of a condition it's in, it might be possible to retrieve some or no data.

Hi Saroop,

Do you not have backups of the containers from the failed node?
