Check your SATA or USB cable connecting the disk if it’s loose. If you are using USB 2, try USB 3. Change USB ports. Don’t forget to change USB or SATA cable just to rule out cable issues.

ok, i can see now, i’ve checked before this post and disk was OK, on next day was disk status SELF-TEST FAILED
trying to copy node to other drive, but looks like rsync had read error on that piece-expiration db… is there some way to fix or replace that db?

#5

Yes. it may be fixed. Just copy blobs without an errors. The databases are not so important - you could lose a stat but will not lose data and thus the node could survive.

#6

so if all other data will be ok, can i just delete that db and node should run?

#7

You can delete this DB, but node would not start. You need to do some extra steps:

  1. Delete corrupted DB
  2. Move all remained DBs to the other place
  3. Start the node, it should re-create databases
  4. Stop the node
  5. Move databases from backup and replace all databases
  6. Start the node.
