Description nchilaka 2016-01-04 02:10:15 EST
Description of problem:
Suppose a hot disk(assume 1GB disk) is about 85%(~850MB) filled(not hit minfree), and I use dd command to create a file which will now exceed the total disk capacity 100%(300MB file), the file create starts off but , after sometime the fuse mount session hangs indefinetly.

This is a regression found during validation of bz#1291566

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

Is this the same issue seen in write-behind ?
Comment 5 Joseph Elwin Fernandes 2016-01-08 12:22:00 EST
Even there is a crash : https://bugzilla.redhat.com/show_bug.cgi?id=1297004
Comment 6 Raghavendra G 2016-01-11 01:04:01 EST
Yes. Hang similar to bz 1219794. Most likely a duplicate. But if you want to confirm, can you take statedump of inodes of the client process after hang? I can confirm with inode statedump.
Comment 7 krishnaram Karthick 2016-01-29 05:19:17 EST
Issue is no more seen in build glusterfs-3.7.5-17.el7rhgs.x86_64.

Steps followed to verify the bug:
1) Create a tiered volume and fill hot disk
2) As new file get created, old files kept demoting
3) No hangs were seen from the client

Moving the bug to verified.
