Symptoms
Backup or storage migration fails.
In Acronis Backup Gateway logs, you see this error:
30-08-17 23:18:12.202 fes_statvfs: '/mnt/vstorage/vols/acronis-backup/storage': {.frsize = 4096, .blocks = 1056846570, .bfree = 50127292}
30-08-17 23:18:12.202 sess#407.req#16547: failed: free storage space check result: -5 (No space/quota exceeded while local file io)
30-08-17 23:18:12.202 sess#407.req#16547: completed with err = -5 (No space/quota exceeded while local file io)
Cause
Your storage is running out of space.
You can check space utilization with the df command:
[root@node-1 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
.....
vstorage://support 590G 566G 23.6G 96% /mnt/vstorage
If there is less than 5% of free space, all write operations are blocked.
In case you are running Acronis Storage migration, if there is less than 10% of free space on your storage, migration is suspended.
Solution
Free up space in your storage or expand it:
