Question
View Exhibit1 to examine the CRS11G disk group when all the disks are online. View Exhibit2 to examine the CRS11G disk group when one disk is offline. Why is the rebalancing not performed and the content of the disk group not empty in Exhibit2? ASM-disk-group-1 (exhibit): ASM-disk-group-2 (exhibit):
Exhibits
Options
- ABecause the disk group is created with NORMAL redundancy
- BBecause the disk repair time attribute is set to a nonzero value
- CBecause the mirrored extents cannot be rebalanced across the other three disks
- DBecause the other three disks have 60% free space, the disk rebalancing is delayed
Explanation
- The COMPATIBILITY.ASM>=11.1 and COMPATIBILITY.RDBMS>=11.1 2. The DISK_REPAIR_TIME is set to non-zero. by default it is 3.6hr. Note: To use this feature, the disk group compatibility attributes must be set to 11.1 or higher. For more information, refer to "Disk Group Compatibility". Oracle ASM fast resync keeps track of pending changes to extents on an OFFLINE disk during an outage. The extents are resynced when the disk is brought back online. By default, Oracle ASM drops a disk in 3.6 hours after it is taken offline. You can set the DISK_REPAIR_TIME disk group attribute to delay the drop operation by specifying a time interval to repair the disk and bring it back online.
