I mean, the real fix here is to support those types of storage ;) I think "no supported file system" explains the situation reasonably well, but open to suggestions of course. > > Maybe we could improve this (at some point in the future) so that the error > does not block the whole panel and we can continue to select another part/number. > Because when two out of three parts block the whole thing, then remembering the > bad one(s), clicking X, clicking File restore->fidx->part->some number is not > ideal IMO. > argh, I already have a fix for that, but apparently I forgot to include my widget-toolkit patches in the series - thanks for noticing! > > * Sometimes the Download button remains enabled when errors (like the previous) > happen and then you get a couple of 0 byte files > yup, should probably disable that as well on error > > * On the respective PBS sometimes this >> 2021-04-22T11:31:01+02:00: starting new backup reader datastore 'test': "/test" >> 2021-04-22T11:31:01+02:00: protocol upgrade done >> 2021-04-22T11:31:01+02:00: GET /download >> 2021-04-22T11:31:01+02:00: download "/test/vm/100/2021-04-22T09:29:17Z/index.json.blob" >> 2021-04-22T11:31:01+02:00: GET /download >> 2021-04-22T11:31:01+02:00: download "/test/vm/100/2021-04-22T09:29:17Z/drive-scsi0.img.fidx" >> 2021-04-22T11:31:01+02:00: register chunks in 'drive-scsi0.img.fidx' as downloadable. >> 2021-04-22T11:31:01+02:00: GET /chunk >> 2021-04-22T11:31:01+02:00: download chunk "/test/.chunks/394a/394a4b4c316868a466fbece11881752a10b31a782d2740ab414c3f48b5fb4e58" >> 2021-04-22T11:31:01+02:00: GET /chunk >> 2021-04-22T11:31:01+02:00: download chunk "/test/.chunks/d628/d62885ad37c7a44a2fa9fdc558e85e89ecf4c9754617fab7e1f491fa3da65d38" > appears and stays there forever and when I clicked Stop >> 2021-04-22T11:47:00+02:00: TASK ERROR: task aborted > it seemed to accept but the circle remained spinning forever again (OK, I only > checked for a couple of minutes). > When you clicked "stop" where? On PBS side? That would be an error in the server code somewhere then. But yes, the task stays active - that is due to the nature of the beast, the VM used to restore keeps the channel open for disk access as long as it runs, once it times out the task should disappear too. > > * Sometimes the PBS also logged >> 2021-04-22T11:42:40+02:00: starting new backup reader datastore 'test': "/test" >> 2021-04-22T11:42:40+02:00: protocol upgrade done >> 2021-04-22T11:42:40+02:00: GET /download >> 2021-04-22T11:42:40+02:00: download "/test/ct/102/2021-04-22T09:39:23Z/index.json.blob" >> 2021-04-22T11:42:40+02:00: GET /download >> 2021-04-22T11:42:40+02:00: download "/test/ct/102/2021-04-22T09:39:23Z/root.pxar.didx" >> 2021-04-22T11:42:40+02:00: register chunks in 'root.pxar.didx' as downloadable. >> 2021-04-22T11:42:40+02:00: GET /chunk >> 2021-04-22T11:42:40+02:00: download chunk "/test/.chunks/ff63/ff63c49eae6b77e2933ea08af0dcf3786e74fc454ac2462ba780f0726c070023" >> 2021-04-22T11:42:40+02:00: GET /chunk >> 2021-04-22T11:42:40+02:00: download chunk "/test/.chunks/261e/261ec247951ab57a51df87c593ae2aaf4f76c671bb94e13245f53ebdf25cfd45" >> 2021-04-22T11:42:40+02:00: GET /chunk >> 2021-04-22T11:42:40+02:00: download chunk "/test/.chunks/3a60/3a60c4eb21123c01a63e981d8f550ba0f99b5e90b97340d384da9f079fa767ed" >> 2021-04-22T11:42:40+02:00: TASK ERROR: connection error: Transport endpoint is not connected (os error 107) > but it looked to me like it didn't really matter?
