Sync gets disabled with "Unable to add filesystem watch."

[jmfitzmaurice]

MEGAcmd version

2.1.0

Operating System/Platform

Synology

Platform version. In the case of Linux, please enter the Linux distribution you are using.

DSM 7.2.2

Steps

1. Photos are in Mega and I want synchronized copies on my Synology diskstation.
2. Issued command "mega-sync /volume1/photo /@OurPhotos"
3. Eventually, an alert appears: "Your sync /volume1/photo to: /OurPhotos has transitioned to state Disabled. ErrorCode: Unable to add filesystem watch."
4. Issuing sync-issues says there are no issues.
5. I cannot determine which files are causing it, let alone why.

Expected behavior

The sync would be established and succeed. Barring that, it would at least indicate which files/folders were causing the problem and causing the sync to be disabled.

Actual behavior

A while after the sync starts, this alert appears: "Your sync /volume1/photo to: /OurPhotos has transitioned to state Disabled. ErrorCode: Unable to add filesystem watch."

Hello @jmfitzmaurice

From the looks of it, MEGAcmd is unable to add a folder to watch the changes that occur in it.

MEGAcmd logs should have further indications on what's going on. You may want to share ~/.megaCmd/megacmdserver.log file with us (via [email protected], referencing this ticket).

Also, ensure you have a high enough number could help, since this could be one reason for failure:

cat /proc/sys/fs/inotify/max_user_watches

Extra: Have you been using MEGAcmd before 2.1.0 ?
