Created attachment 16068 [details] Output of the error in commons beta lab Error: Could not read or write file "mwstore://local-backend/local-public/3/3d/VisualEditor_save_dialog-he.png" due to insufficient permissions or missing directories/containers. Could not store file "/tmp/UgKpr4" at "mwstore://local-backend/local-public/3/3d/VisualEditor_save_dialog-he.png". I had got similar error while uploading images through API: { "servedby": "deployment-mediawiki02", "error": { "0": [ "backend-fail-usable", "mwstore://local-backend/local-public/6/68/VisualEditor_Insert_Menu-he.png" ], "1": [ "backend-fail-store", "/tmp/owzHOG", "mwstore://local-backend/local-public/6/68/VisualEditor_Insert_Menu-he.png" ], "code": "internal-error", "info": "An internal error occurred" } } Scenario: * I go to one of the image which I had already uploaded in commons[0]. * I click on upload new version of this file at the bottom of the page. * I add a new image[1] by browsing my file system and I click Upload file. * Then I get the error reported above or the image in attachment. - [0]: http://commons.wikimedia.beta.wmflabs.org/wiki/File:VisualEditor_save_dialog-en.png [1]: http://commons.wikimedia.beta.wmflabs.org/w/index.php?title=Special:Upload&wpDestFile=VisualEditor_save_dialog-en.png&wpForReUpload=1
Showing my ignorance: Do you have the right permissions? I apparently don't as I see "You cannot overwrite this file." on that and other images on the beta cluster commons.
Let me know your user names and I can upgrade your privileges on beta labs.

Looks like the images which were uploaded before(i.e. before we got the some problems with beta labs recently) have this problem. I tried updating the image which was uploaded yesterday and it works fine.
cc'ing ori/bryan in case this was an effect of hhvm permission weirdness.
Beta uses the NFS shared directory /data/project/upload7 to store images. I just did a permissions check on this directory for sub-directories that are not world writable and found a bunch. This is a likely cause of at least some of the failures. To check: $ cd /data/project/upload7 $ find . -type d ! -perm -o=w ... lots of dirs output here ... To fix: $ cd /data/project/upload7 $ sudo find . -type d ! -perm -o=w -exec chmod 0777 {} + A hack fix would be to cron this fix somewhere in beta. A better fix would be to kill NFS and use swift for image storage.
