Hi Damir (or anyone else affected by this that may be reading the bug),
If you get a chance, could you please test the kernel that is in
-proposed to verify that it resolves the issue for you? There are
instructions in comment #12 for verifying this for Bionic or if you're
using Xenial, the

Hi everyone,
I was just curious if anyone's had a chance to test out Kai-Heng's test
kernel from comment #8?

I can confirm this affected me as well. My RAID-10 is on a separate
filesystem from the Operating System's SSD -- I have the RAID-10 mounted
at '/raid10' on my server. My application is installed on the non-mdadm
SSD at '/opt' but it reads/writes/executes files from the '/raid10'
filesystem (made
This issue is gone after we migrated from XFS to EXT4, so it is

Title:
Linux md raid-10 freezes during resync
To
Same problem here reproducible on Ubuntu 18.04 LTS. SATA RAID 10 with
XFS filesystem. On each reboot the RAID does a resync. Any operation on
the RAID before the resync is finished causes the process to hang. Might
be also associated with another issue that causes the resync every time
on boot.
Same here, md raid10 (not sure if its important but xfs, hung 3 times in last 2
days).
It seems that a combination of md raid10 check + I/O (maybe XFS-specific, I
dunno, but both original poster and us seem to use XFS) frequently hangs on
kernels that are newer than Ubuntu
Status changed to 'Confirmed' because the bug affects multiple users.
