EX4100 getting stuck ar GUI, Wont let me copy random files and folder and won't reboot/hibernate

arslan1337 · November 17, 2023, 1:03pm

EX4100 stopped working and won’t power off. The web interface opens but whenever I do something on it, it gets stuck at updating. If I access folder share, it randomly gets stuck on some folders and does not let me copy random files
It will not power off or restart from the web interface. I cannot even get system logs from Support. Firmware: 5.27.157

arslan1337 · November 17, 2023, 2:33pm

5.27.157

Cerberus · November 17, 2023, 2:36pm

Perhaps the recent firmware update triggered the indexing processes? The EX4100 is notorious for unexplained system “hangs” and sluggish performance under heavy workloads.

Otherwise, have you tried rebooting?

arslan1337 · November 17, 2023, 2:59pm

I took a backup via veam last night, which triggered all this I think cause it was a lot of data around 300 gb. Dont, know if it completely uploaded. So I also think its indexing.

I stopped restdsk process which I think was indexing via SSH, but looks like it worsened it. I then also forced restart but it also looks like it worsened the issue too. I am lost.

Indexing will bring an EX4100 to a standstill rather quickly.

Have you checked the hard drives for errors? Don’t trust the dashboard, it omits critical information.

For all 3 drives, it says a bunch of other things and this:

The fourth drive /dev/sdd is showing signs of problems, where the following S.M.A.R.T. attribute should be zero.

UDMA_CRC_Error_Count - 1

The WD Blue WD20EZAZ drive is mismatched from the other WD Red WD40EFRX drives, plus it uses SMR technology, which is NOT suitable for use in RAID arrays. Consider replacing the drive ASAP.

arslan1337 · November 17, 2023, 3:59pm

Thank you so much for your time and efforts. I cannot thank you enough. I will definitely do it ASAP.

It should be hot-swappable and RAID will rebuild automatically, right?

Cerberus · November 17, 2023, 4:02pm

You should power off the EX4100 before replacing a drive. RAID rebuilds may or may not be automatic, it all depends on how you have it configured via the dashboard. Even then, it sometimes doesn’t work as expected.

arslan1337 · November 17, 2023, 4:06pm

Thank you so much, Cerberus.
