Reduce XFS filesystem on Linux

Hello friend ,

today i am going to discuss on XFS file system Limitation and that limitation is Linux admin cant reduce XFS file system online. after knowing this limitation i am still thinking about what is that preventing XFS shrink ? also is there any alternative way we can reduce size of XFS file system.

Yes, we can reduce size of XFS , but for this downtime needed.

Step 1: Backup existing file system backup using "xfsdump" 

Step 2: Then umount XFS file system.

Step 3: Then remove LV .

Step 4: Create required size LV.

Step 5: Mount File system.

But here Linux admin require downtime.
