You can control the path where the gallery saves/loads it data from.

Does a galleriessubdirectory of $HIPalready exist? If so, do you have permissions to write into it? If not, do you have permissions to create it?

It auto create the "galleries" folder,"*.stage" folder and "rendergallery.db" file ,but the file is 0kb,it says no permission

If you delete that 0kb file and try again do you end up in the same position, or does it now work? We've been unable to reproduce anything like this so far.

I'm having the same issue on Rocky Linux 9.3, 20.0.653. If I delete the 0kb rendergallery.db file, it complains of the same error, creates the empty file again, and goes to in memory storage.

Did anyone manage to solve this? Rocky9.5 + Houdini 20.5.487, still 0kb and the same error message. Everything works if the gallery location is set to a local disk instead of my NAS. But everything else (rendering, caching, etc.) works on the NAS.

Hi, I had the same issue with my Linux Mint machine, but I solved it yesterday!


✅ Issue

Houdini's Render Gallery uses SQLite to store data. When saving to a NAS (Network Attached Storage), users may encounter errors such as:

・ database is locked (5)

・ Permission Denied

This happens because NAS file locking mechanisms interfere with SQLite’s required locks.


✅ Causes

1. CIFS (SMB) mounts do not support SQLite’s byte-range locking by default.

2. Houdini’s Render Gallery relies on SQLite, which cannot function properly if locks cannot be acquired.


✅ Solutions: Add nobrl Option for CIFS (SMB) Mounts

If using CIFS (SMB) to mount the NAS, follow these steps:

1. Unmount the existing NAS mount:

sudo umount /mnt/NAS

2. Remount it with the nobrl option:

sudo mount -t cifs //NAS_IP/your_share /mnt/NAS \
-o username=your_user,password=your_password,uid=1000,gid=1000,vers=3.0,nobrl

3. To make this change permanent, edit /etc/fstab:

sudo nano /etc/fstab

4. Add the following line:

//NAS_IP/your_share /mnt/NAS cifs username=your_user,password=your_password,uid=1000,gid=1000,vers=3.0,nobrl 0 0

Apply the changes:

sudo mount -a


If you use SMB to mount NAS, it might help.
