My attempt to change from (in smartctl output form): Supported LBA Sizes (NSID 0x1) Id Fmt Data Metadt Rel_Perf 0 + 512 0 2 . . . to: Supported LBA Sizes (NSID 0x1) Id Fmt Data Metadt Rel_Perf . . . 3 - 4096 0 0 . . . reported: # nvmecontrol format -f 3 nvme1 nvmecontrol: format request returned error but afterwards shows: Supported LBA Sizes (NSID 0x1) Id Fmt Data Metadt Rel_Perf . . . 3 + 4096 0 0 . . . It also shows: Media and Data Integrity Errors: 0 Error Information Log Entries: 0 Error Information (NVMe Log 0x01, 16 of 64 entries) No Errors Logged dmesg -a shows: # dmesg -a | tail -7 nvme1: Resetting controller due to a timeout. nvme1: event="start" nvme1: event="success" nvme1: aborting outstanding admin command nvme1: FORMAT_NVM (80) sqid:0 cid:15 nsid:ffffffff cdw10:00000003 cdw11:00000000 nvme1: ABORTED_BY_REQUEST (00/07) crd:0 m:0 dnr:1 p:0 sqid:0 cid:15 cdw0:0 nvme1: done aborting outstanding admin Is this a problem for use of the media? Did it likely finish what it was doing? If it did not finish, what may I do about it?
