My Cloud OS5 - Indexing taking forever

@lmcjecy the following FAQ helps explains what happens after the indexing has completed.
IE: After the indexing has completed, the generating of thumbnail previews is still occurring.

So when will Wd add an option not to have the useless thumbnails and save everyone including themselves a whole lot of grief…
By the way, are they held as blobs in the database? Is that why I read about someone with a 1GB database?
In the meantime Nextcloud is looking good and I’ll post up how to get it going in a few days.

To be precise WD created Unix partition of 928Mb (almost 1 Gb) in my case. Of this, only 121Mb is used right now. Regardless this 928 Mb is “space reserved” from the disk. This is disk space that you will probably not be able to use to store your own data (pictures and all). (Unless this partition can be reused by some WD trick or shrink dynamically which I have not seen in Linux yet!)

df -h /mnt/HD_a4

Filesystem Size Used Available Use% Mounted on
/dev/sda4 928.9M 121.9M 791.0M 13% /mnt/HD_a4

You are right - but actually its the same in OS3. I never looked before…

You could try FTP with a VPN set-up ( better for security )

Time to dump WD NAS they have become garbage. OS5 rollout so poor and destructive, I'm switching brands to Synology after much research

After 27 days indexing 255000 photos, the WD MY CLOUD EX2 ULTRA NAS is ready!
Firmware updated twice helped.

sda and sdb disk loads are down to 0% utilisation !

All the I/O and CPU are available ! Let’s see what this unit can do…

Linux ssh commands. See last %util column.

iostat -x 30

load average: 0.02, 0.03, 0.05

Hi everyone, I’m in the same boat as everyone here. Indexing is completed, but I guess I’m still in the process of generating thumbnails that I could honestly very well live without. I set my hard drives to turn off overnight as I couldn’t sleep with fans going at 10000RPM…Very frustrated with the new update!! My question : Is there linux command or any other trick to assess how much longer this will go for ??

My Cloud PR4100 32TB (64 TB RAID 10)
I’m in 4th week of INDEXING! @ 45% i have 23 TB data and 9TB free space.

this is the response from WD support:

Dear Max_T,

Thank you for contacting Western Digital Technical Support. My name is Jason T.

I understand you are experiencing issues with your WD My Cloud PR4100 after updating to My Cloud OS 5. I apologize for the inconvenience caused to you.

The existing My Cloud OS 3 indexing cannot be used after updating to My Cloud OS 5. A new index must be created to view your content using remote access in the My Cloud OS 5 web and mobile apps. This process can take a few hours up to a few days to complete depending on the size and type of the data. Thank you for understanding and we apologize for any inconvenience this issue may have caused.

I moved to a Synology NAS. What a better all around experience


Please ensure your PR4100 is on firmware 5.06.115

Thanks, Yes it is. I check every day the progress. an extremely annoying slow process …

@Max_T If your firmware is already on 5.06.116 and the indexing has not completed,
please collect the system logs, send to support and let me know the case number.

I downloaded the report but can’t find where to upload the zip file on the WD website.
I already have a case Reference #: 201125-000111

Login to the portal and attach the file.

where ? i cant find anywhere to upload in the support portal !

found it


OK. I’ll try, and give you a last chance…

Thank you, WD. Since SIX HOURS MyCloud Mirror is no more accessible.


VERY BAD START :frowning: :frowning:
Indexing started… 2 minutes to open “Settings”.
Then I tried to change “Energy Saving” settings. Grey screen since TEN MINUTES !!!
:sob: :sob:
Everything very very SLOW!
