JorgeB Posted May 5, 2020 Share Posted May 5, 2020 Cache filesystem is corrupt, best bet is to backup, re-format and then restore the data. Quote Link to comment
harshakavuri Posted May 5, 2020 Author Share Posted May 5, 2020 Could you tell me the procedure for reformatting the cache drive. Thanks a lot for the help. Quote Link to comment
JorgeB Posted May 5, 2020 Share Posted May 5, 2020 Easiest way is to clear it with blkdiskcard (after the backup is done) -stop array blkdiscard /dev/nvme0n1 -start array -there will be an option to format the cache Quote Link to comment
harshakavuri Posted May 5, 2020 Author Share Posted May 5, 2020 I am in the process of making a backup of cache. Once done i will use the command, and once again thanks for the help. Quote Link to comment
