Successfully updated my F4-425 Plus to TOS 7.0.1169.

The update completed successfully and the NAS is operating normally so far. No issues noticed after the update.

Shortly after updating, I was also pleasantly surprised to see a major Jellyfin update available in the App Center. Thank you TerraMaster for making this update available — it's great to see Jellyfin being kept up to date.

J'ai effectué la mise à jour. Il existe toujours des instabilités dans le partage "SMB" pour les utilisateurs "Guest".
A noter aussi que les connexions "SMB" avec le compte "super administrateur" ne sont plus possibles. Seul un compte "administrateur" classique permet de se connecter.
En finalité, les partage "SMB" sont toujours aussi instables et compliqués depuis le passage à TOS 7. Que ce soit depuis des machines Windows que depuis d'autres NAS (Qnap et Synology dans mon cas). Je suis obligé régulièrement de refaire des partages "personnalisés" et de cocher la case "droits hérités aux sous-dossiers" pour retrouver des accès, comme si tout était volatile.Il y a visiblement des incohérences dans le code de TOS 7.0 et le programmeur semble complètement perdu. Renforcer la sécurité, c'est bien. Mais si cela se traduit par des instabilités constantes, c'est franchement agaçant.
Le module "SMB" est à remettre à plat..

Applied to stand-alone TNAS (remains most up to date) & will install to testbed TNAS units during phase 2 if no issues are observed.

Haven't allowed production units @ clients to accept any of the recent updates since the NTP issues.

The update completed successfully, everything is running as normal.

All three devices updated w/o issue. Although there seems to be a math issue on the processes screen

I regret that I updated to the new Jellyfin. Is there a way to rollback to the old version?

Unfortunately, we have not been able to reproduce the issue you reported in our lab, and no other users have reported anything similar. Could you try clearing the SMB cache, checking whether your network connection is stable, and verifying if there are any applications running with high I/O load?

Same! My disks have been chattering away in what I assume is metadata refresh related. My entire system has crawled to 99% utilization. It's been 30 minutes

Updated Jellyfin right before upgrading to 1169, did not know Jellyfin is running migration, lucky after the reboot Jellyfin starts continue working with running migaration. Let me see if there is any problem after the upgrade. Anyway my machines are F4-424 traid with one D4-320 Traid 2 and another D4-320 with four single volume drives. BTW the migration took about 10 minutes and Jellyfin works fine. Keep up the good work Terramaster.
