SmartDisk crashing and going offline in netvault
After restarting the SmartDisk services SmartDisk can appear online but shows spaced used as 0KB and deduplication ratio as infinity: 1
SmartDisk dump shows failure when deleting segments in the store during expiration of backups or during Garbage collection as seen below in stracestorageservice trace extract.
We also see file system error in the Linux messages file found in dump folder \var\log. This points to the SmartDisk store having FileSystem problem.
