When logging in, an error similar to the following appears:
EXT4-fs (dm-0): delayed block allocation failed for inode 393414 at logical offset 31 with max blocks 2 with error -28
This should not happen!! Data will be lost
Total free blocks count 0
Free/Dirty block details
Block reservation details
The disk or volume is full and either needs to be expanded to add more space, or data needs to be removed from the disk to free additional space.
If the disk or volume is full the policy server may not function as necessary.
Once space is cleared up or the drive/volume is expanded, please restart the policy server so the changes can take affect and the policy server can return to working as expected.
