Issues Fixed in Lightbits 3.8.3

AI Tools

ID	Description
33173	data-layer: under rare conditions, deleting snapshots could lead to rebuilds not starting and volumes being stuck in degraded/read-only protection states. This issue is fixed in 3.9.1 and 3.8.3 and upgrading is strongly recommended.
32970	userlbe: there is a possible race between the exporter accessing some metrics and volume deletion. This race, when hit, could cause a Lightbits node to stop serving I/Os. The failure signature in the journal is a large number of errors `Failed reallocating adirbuf for 'md_N_nsid_M_ver_V` . This issue is fixed in 3.8.2 and later 3.8.x releases, and in 3.9.1 and later 3.9.x releases. Upgrading is recommended.
32950	node-manager: there is an extremely rare race in the service's startup flow, that combined with a very rare chain of migrations of the same volume, may in theory lead to incomplete rebuilds. This issue is fixed in 3.9.1 and 3.8.3 and upgrading is strongly recommended.
