This is addressed in 3.0.35. Please generate the diagnostic logs (HTML UI -> System Page -> Run Diagnostics) before and after the upgrade and send them across to [email protected] > > As for the behavior - all drives just go offline in TSM and the only way to > bring them back online is quadstor service restart. The drives should not have gone offline at the client/server OS level. i.e the /dev/IBMtape[n] or similar devices should be accessible The next time this occurs does a manual "UPDATE PATH" work ? For example update path QUADSTOR1 drive0 srctype=server desttype=drive library=lib0 device=/dev/IBMtape0 online=yes The command is similar to the define path command but with the trailing "online=yes" Follow up with a "q path" command to see if all paths are online > > > On Wednesday, June 5, 2019 at 11:32:48 AM UTC+3, quadstor wrote: >> >> Hi, >> >> Service shutdown/load time has been addressed in 3.0.35 >> https://www.quadstor.com/vtl-extended-edition-downloads.html >> Please generate diagnostics logs before and after the upgrade >> >> The shutdown or load can be slow based on the speed of the master disk >> and in older installations where all the deduplication tables are not >> created upfront. >> >> When an out-of-space condition occurs, any pending writes are >> terminated with error.
