The process named "convert" in WD My Cloud EX2 causes severe performance and availability problems as well as unnecessary wear of hard drives. After putting many files into the EX2 unit, the convert process begins to consume CPU 100% and cause many unnecessary I/O activities on the hard drives until the owner reboots the unit.
Please implement solution to this also for EX2 My Cloud Device!
Currently on the EX2, we have the ability to create remote backup jobs. Once created, however, there is no way to EDIT the job. In order to change any of the parameters on the job, one must delete the current job, and create a new job with the same job name as the one deleted to prevent a new copy of the source data to get backed up to the destination drive.
Please add the abiltiy to edit any one of or all the parameters of an existing Backup Job:
Add / remove shares
Change backup "TYPE" from Copy to Synchronize (or visa versa)
Change job from Autoupdate OFF to Autoupdate ON (or visa versa)
Repair the software bug in the dashboard webfile viewer so users other than Admin can use it remotely to transfer files.
Curently you can enable dashboard access and forward port 80 or 443 (443 for secure html) to then access the EX2 or 4 directly via your WAN ip. This allows you to use the built in web viewer app to upload and download files when you are away from your home. Other users that you have added to the EX4 can log in via there own username and password and they will be shown a limited version of the dashboard with only the viewing rights to the directories that you have assigned them. However, they can not download, or upload anything which makes this useless for sharing files.
So to summarize, remote dashboard access as the admin works perfectly, remote dashboard access as a sub-user is useless.
I have also noticed that if I login to the admin account, then logout and back in as a subuser on the same PC, the sub-user account works perfectly. However I can't go to my users homes and login then logout so they can have access...
Getting this fixed would solve a lot of file sharing problems for everyone.

I would like to have the ability to backup my enitre EX4 to an external USB drive. I know the feature is already in the unit, but you have to schedule one folder at a time, so it would be nice to schedule the whole unit, and then only have it backup the files that have changed, and not the whole unit. It could be kept in one folder on the USB drive, instead of creating individual folders with dates and times. Also would like to see the ability to remove permissions from the USB backup share so that you can restrict who sees all the data from the EX4.
I am using my EX4 as more storage for my backup server. I'm doing disk to disk backups, and then disk to cloud with a 3rd party.
My disk to disk is something I built, which has a few other people using it for fairly large setups. It's simply rsync with hard linking between incrementals. I'm not sure if hard linking is working at all with Samba though. I'm bouncing between projects here like a mad man.
To give SMB access to my previous NFS share, I had to do the following. It would be good to see these as options or changes in future firmwares, so I don't have to do it manually in the shell. I had to grant root access to samba, because I back up almost everything, and they can be owned by any local user. If I back up the entire filesystem, lots of files are owned by root (obviously), so Samba allowing root is essential. It would be a nightmare to restore and guess at ownerships for every file on the system.
I gave this disclaimer on my post, so you guys will (hopefully) not get support requests for changes I mentioned.
"Note to everyone else. Don't do any of this. I had to log in via SSH and manipulate things directly. I'm a professional, and take all liability for my own mistakes."
If I can be of any more help, feel free to email me. I believe admins can see my email address on my profile. If you're at WD and can't get my email, get with me and we'll figure it out. I'm sure this is all clear enough for anyone building the firmware. If you want me to try something in my environment, I'm willing to consider it. I work with this stuff all day every day, so I generally know if a change is dangerous.
There's a bug with my changes. I can read all the root-only files now. I can't write to anything. I'm back in to fix that. I'm sure it's one stupid flag. samba.conf can be annoying.
1) Allow the user root to be accessed via the user panel, and add it to the smbpasswd file.
Obviously the local user root already exists. I added it to the smbpasswd file with: smbpasswd -a root
And I also set the local user password with: passwd root
2) Make root a valid option as a user to be allowed to the share. Allow root to be added to the valid users list.
3) Change /proc/sys/dev/raid/speed_limit_* . 1000 is way too low with 16TB. After the firmware update, it wanted to rebuild the array, and will take 11 days. I changed them to 99999999 (arbitrarily high number) . Now it claims 2.54 days. That could be catastrophic if someone had flaky power. We've been having short power outages here, but the UPSs stayed up the whole time. If we had a long outage and the generator didn't kick on (or if I was an average home user) dropping power during a rebuild could fail the array. I don't think you want to try to explain over the phone to a novice user how to reassemble a failed array.
4) I would have liked it if you had built busybox with chattr. Tell whoever builds it, they'll understand. I wanted to "chattr +i smb.conf", so nothing would accidentally change my settings back. I already tested, and if i make any unrelated changes, it reverts them to your settings. I made a backup, so it won't be a big deal if it changes in the future.
I only got the EX4 because it was cheaper than building out my own machine to do local storage. As far as that goes, it's cute, and seems to work well. All in all, it doesn't look bad from the inside.
And, thank you for having ssh as an option. i'd hate to have to try to root this thing without it.
I store tens of thousands of pictures on my WD EX4. The thumbnails take up too much space and it also decreases performance. I copied over about 30,000 images (827 GB) and the thumbnail creation process took over 24 hours! Thank goodness a lot of the images were still in RAW format that did not get thumbnailed, othersise it would probably still be running!
I don't need the thumbnails in the hidden folder (.wdmc), nor do I want them. I understand some people want them, so PLEASE add a configuration switch to disable the process that creates them. You could do this on a Share by Share basis so if someday I want some of my images thumbnailed I can put them in a share configuresd to create them automatically.
I have seen a lot of discussions around disabling some services, but it would be better if you just added a configuration switch.
