Known Causes

3 known causes
⚠️
Diskgroup Fragmentation
Frequent file creations and deletions within the ASM diskgroup can lead to fragmentation, making it difficult to find a single contiguous block of the required size.
⚠️
Large Allocation Request
Attempting to create or extend a file, snapshot, or volume that requires a very large contiguous extent that exceeds the largest available free space block.
⚠️
Inadequate Diskgroup Sizing
The ASM diskgroup was originally provisioned with insufficient total capacity or has not been expanded to meet current storage demands, leading to overall space constraints.
