FUSE v2¶
arv-mount (source:services/fuse) is our Python-based fuse mount that has been used in production for years.
arvados-client mount (source:lib/mount), aka "fuse v2", is our Go-based fuse mount that is currently flagged "experimental" and is missing some of arv-mount's features. Nearly all of the v2 functionality is provided by the same "filesystem" code used in production by keep-web to provide WebDAV and S3 services.
Ultimately we aim to retire arv-mount and provide arvados-client mount as a faster, more reliable drop-in replacement.
For some use cases, v2 will be usable before reaching full feature parity.
| Before supporting/recommending READ-ONLY production use | |
| ✅ | Manual stress tests |
| Automated stress tests | |
| Listen to websocket and sync remote changes | |
| Ensure memory footprint of a long-running mount doesn't expand indefinitely | |
| Ensure inodes don't change in a way that confuses kernel (see #12870) | |
| Before supporting/recommending READ/WRITE production use | |
| Sync local changes automatically (on timer?) even if fsync is not called | |
| Before replacing arv-mount in crunch-run use case | |
| Option to mount temp collections at specified paths | |
| Option to mount by_id and by_pdh magic dirs at specified paths | |
| Option to specify cache directory and max size | |
| Option to specify storage classes for writes | |
| Option to write crunchstat metrics at specified interval | |
| Before replacing arv-mount entirely | |
| Accept project/collection/tag filters on command line | |
