FC[7507]: Mutex file check failed with error : 103

01e9 commented 5 years ago

I am pulling my hair for a few hours.

I do:

Start sync container
The directory on another machines is synced ok
I add a new file in container (via docker cp or mount the same volume in another container)
The new file causes error and I don't receive it on other machine (only after container recreate it works again)

I tried different combinations, with/without volumes, but still get the error.

What may be the cause?

This error happens with 2.6 and 2.5. It works with resilio/sync:release-2.4.5.

@arteniioleg this is not Docker related issue, according to the log provided there is some issue with /mnt/mounted_folders/sync/.sync folder, in particular with service files inside .sync folder. Please contact support and provide full log to analyze the issue https://help.resilio.com/hc/en-us/requests/new?ticket_form_id=91563

This issue is hard to reproduce with regular resilio usage on PC, so reporting it will be confusing for testers/developers. I will keep this issue open until I will have enough motivation and time to create a full docker-compose configuration to reproduce it easily.

@arteniioleg got it, once it's done please contact support directly using the link provided. Thanks.

My bad.

I use Resilio for backups. After creating a new backup archive I delete old files with this command

docker exec ${CONTAINER} find /mnt/mounted_folders/sync -mtime +30 -type f -delete

and it deleted /mnt/mounted_folders/sync/.sync/ID because it scanned files recursively.

The fix is to add -maxdepth 1

docker exec ${CONTAINER} find /mnt/mounted_folders/sync -maxdepth 1 -mtime +30 -type f -delete

bt-sync / sync-docker
