(but that could be done later as well, given that it is marked as internal already - it might also increase build times, which might be an argument against it..) - creating a second removable datastore on a device fails, since the create_datastore API endpoint has a wrong check (see comments on corresponding patch) - pre-existing: while creating a datastore, we hold a lock on the config which can cause all sorts of operations to run into a (lock) timeout, the lock scope could maybe be reduced (for removable datastores, creating the chunk store might take a long time..) - unmounting a datastore over the UI spams the log with: 6:08:17 yuna proxmox-backup-proxy[812419]: GET /api2/json/admin/datastore/removable2/status: 400 Bad Request: [client [::ffff:192.168.16.37]:47734] Removable Datastore is not mounted - unmounting over the UI, then pulling my USB drive logged the following: Nov 21 16:09:04 yuna kernel: EXT4-fs (sda1): shut down requested (2) Nov 21 16:09:04 yuna kernel: Aborting journal on device sda1-8.

I didn't look at the UI patches, just did a cursory test drive of the resulting UI! On November 13, 2024 4:00 pm, Hannes Laimer wrote: > These patches add support for removable datastores.
