I am getting the error regarding the space available in /ssd. I am using a latest version of cryosparc.

raise RuntimeError(
RuntimeError: SSD cache needs additional 144.70 GiB but drive has 122.37 GiB free. CryoSPARC can only free a maximum of 0.00 B. This may indicate that programs other than CryoSPARC are using the SSD. Please remove any files on the SSD that are outside the /ssd/cryosparc_cache/instance_spgpu:39001 folder or disable SSD cache for this job.
Is there any command or tips or script to deal with cache that quickly covered all space of SSD? I would really appreciate for that.
but now you may want to change the File lifetime or perhaps clean up some jobs. I do not think clear intermediate results will clear the SDD cache.
In your case, if the SSD is full it would be good to know how to manually clear it. The old way was easier since you could just remove caches for old projects. Most of the scratch space was taken by particle stacks anyways.
@Suresh Under normal circumstances, file copying to and file removal from /ssd/cryosparc_cache/instance_spgpu\:39001 should happen automatically. Manual removal should not be required.
If the filesystem that stores the /ssd/cryosparc_cache/instance_spgpu\:39001 directory is shared with other uses/functions, in addition to particle caching for the CryoSPARC instance on spgpu at port 39000, those other uses may reduce the space available for particle caching.
To provide a clearer picture of the situation, please can you run these commands on the CryoSPARC worker computer and post their outputs:
sudo du -sh /ssd
sudo du -sh /ssd/cryosparc_cache/
du -sh /ssd/cryosparc_cache/instance_spgpu\:39001
df -h /ssd/cryosparc_cache/instance_spgpu\:39001
@Mark-A-Nakasone In CryoSPARC v4.5.3, if no CryoSPARC jobs are running, it is safe, but should normally not be required, to delete the instance_${CRYOSPARC_MASTER_HOSTNAME}:$((CRYOSPARC_BASE_PORT+1))/ subdirectory under the Cache Path of a CryoSPARC worker.
