Description shylesh 2011-12-12 09:43:18 UTC

Description of problem:
Pathinfo extended attribute shows latest set block size for the files created with different block size

Version-Release number of selected component (if applicable):
3.3.0qa15

How reproducible:
Always

Steps to Reproduce:
1.Create a stripe volume and mount it 

2.Create some file on mount points , now these files have block size 128KB

3.Change the block size for the volume through volume set, say 1MB

4. Now create some files on the mount point, these files should have block size as 1MB

5. Now execute the command " getfattr -m . -n trusted.glusterfs.pathinfo * "

Actual results:
For all the files block size shown as 1MB

Expected results:
Block size should be same as the size with which the file was created

Actually it's showing 64MB no matter whatever the blocksize is

Now another issue is while verifying this bug

1. Created a stripe volume , touched some files , block size was default
2. changed the block size using volume set to 2MB, whatever the files created after this and previously created files has proper block sizes.
3. Now i changed the stripe size to 8MB, files created after this still shows 2MB as block size

so reopening the bug

If this is on 3.2, this is known problem as the update is not handled in the reconfigure part. I'll get look that up. It should be fine in master, can you please check that.

Also, for now you remount the volume and then check the block sizes for freshly created files.

Sorry, my bad. The fix in the reconfigure part is still not in master yet.

Verified on 3.3 master working fine.
