Having this error on your R1Soft policy for a one or several servers?
Error replicating device <PARTITION_MOUNTPOINT> (<PARTITION_UUID>)
Protocol error, expected request finished
Encountered <0000> read failures!
Snapshot failed with error ‘FILE IO ERROR’!
An exception occurred during the request. Backup failed due to snapshot error! The next replication will force a full block scan.
This is likely due to a filesystem 100% full on one of your partition/mountpoint!
Login on the server and issue the following command :
df -h
The output should give you something like this :
Filesystem Size Used Avail Use% Mounted on /dev/sda2 48G 28G 18G 62% / /dev/sda8 352G 201G 133G 61% /cache /dev/sda7 1.9G 1.9G 0 100% /var/log /dev/sda6 2.9G 92M 2.6G 4% /tmp /dev/sda5 946G 685G 213G 77% /home /dev/sda1 99M 30M 65M 32% /boot tmpfs 9.8G 0 9.8G 0% /dev/shm
In this particular case, we can see the “/var/log” partition is full. Check the output and make some space on the partition that show a 100% usage.
Then run the backup policy again and your backup should complete successfully.
