Description of problem:
In a 3 x (4 + 2) = 18 distributed disperse volume, fuse mount point hung after self healing of failed disk files and folders.

How reproducible:
100%

Steps to Reproduce:

1. create a 3x(4+2) distributed disperse volume across nodes
2. FUSE mount on the client and start creating files/directories on the following hierarchy
   /mountpoint/folder1/file1
   /mountpoint/folder2/file2
   /mountpoint/folder3/file3
 
3. simulate the disk failure by killing pid of file2 disk on any one node and add again the same disk after formatting the drive
4. start volume by force
5. self haling adding the file2 with 0 bytes in newly formatted drive
6. wait more time to finish self healing, but self healing doesn't happen. The file2 resides on 0 bytes
7. Try to read file2 from client, now the file name with 0 byte is tried to recovery and recovery will be completed. Get the md5sum of the file2 with all storage nodes and the result is positive
8. Now, bring down 2 of the nodes other than failed drive.
9. Now try to ls the mount point, mount point will hang

Actual results:
mount point hung

Expected results:

Mount point should list all the folders

Try to simluate disk failure and add again same disk.After recovery put ls on client mount point, mount point will hung.

Comment 1 Pranith Kumar K 2015-08-05 01:54:28 UTC 
hi Backer,
    Could you try this test with 3.7.3 please. We fixed 2-3 hang bugs so it would be great if you could let us know if it still happens. Meanwhile Xavi and I are going to work on 1235964 you raised. Do you hangout on #gluster IRC? It would be great to know your feedback about 3.7.3 to see what you think about the stability of EC. We feel EC is almost ready for production with 3.7.3 release based on our tests in lab.

I have tested the 3.7.3 as well as 3.7.2 nightly build( glusterfs-3.7.2-20150726.b639cb9.tar.gz) for the I/O error and handout issue. I found that 3.7.3 has the data corruption issue which is not present is 3.7.2 nightly build( glusterfs-3.7.2-20150707.36f24f5.tar.gz). Data has been corrupted after replacing the failed drive and running the self heal. Even we find the data corruption after the recovery of node failure ,When unavailable data chunks has been copied by proactive self heal daemon. You can reproduce the bug through the following steps

Steps to reproduce:
1. create a 3x(4+2) disperse volume across nodes
2. FUSE mount on the client and start creating files/directories with mkdir and rsync/dd
3. Now, bring down 2 of the nodes(node 5 & 6)
4. write some files(eg filenew1, filenew2). The files will be available only on 4 nodes( node 1,2,3 & 4 )
5. calculate the md5sum of filenew1 and filenew2
6. Now bring up the failed/down 2 nodes( node 5 & 6)
6. Pro active Self healing will create unavailable data chunks on 2 nodes (node 5 & 6).
7. Once finish the self healing, bring down another two nodes (node 1 & 2)
8. Now try to get the mdsum of same recovered file, there will be a mismatch in md5sum value.

But this bug is not available in 3.7.2 nightly build (glusterfs-3.7.2-20150707.36f24f5.tar.gz)

Also i would like to know, why the proactive self healing is not happening after replacing the failed drives. I have to manually run the volume heal command for healing the unavailable files.

hi Backer,
     Thanks for the quick reply. Based on your comment, I am assuming no hangs are observed. Auto-healing of replace-brick/disk-replacement is something we are working for 3.7.4, until then you need to execute "gluster volume heal ec2 full".

As for the data corruption bug, I am not able to re-create it:
Let me know if I missed any step:

(In reply to Backer from comment #6)

Thanks for the detailed description. We have been able to identify the cause of this problem. Self-heal doesn't correctly heal files on volumes where the number of data bricks is not a power of 2.

I'll send a patch to solve this.

commit fc3da7299dc2adaf66076bfbfebe4a87582f7008
Author: Xavier Hernandez <xhernandez>
Date:   Fri Aug 7 12:37:52 2015 +0200

    cluster/ec: Fix write size in self-heal
    
    Self-heal was always using a fixed block size to heal a file. This
    was incorrect for dispersed volumes with a number of data bricks not
    being a power of 2.
    
    This patch adjusts the block size to a multiple of the stripe size
