--- Comment #25 from SATHEESARAN <sasundar at redhat.com> ---
Tested with RHGS 3.5.4 interim build ( glusterfs-6.0-51.el8rhgs )

1. Created a replica 3 volume and enabled sharding
2. Created 2 fuse mounts
3. Created a file of size 512B from one of the fuse mount
4. From one fuse mount truncate that file to 0
5. From another fuse mount truncate the same file to 0 again.

I/O errors are noted as sharding doesn't support truncate from day1.
But there are no crashes observed.

Also tested this scenario in RHHI-V setup, with 10 VMs running workloads
There are no issues seen.
