What were you trying to do that didn't work?
On systems that boot from SAN over NVMe-TCP or NVMe-FC, it is quite easy to make the system inoperable by issuing a 'nvme disconnect-all". For instance, after issuing the disconnect on a system which boots over NVMe-FC, the console reports the following:
[ 103.827323] block nvme1n1: no available path - failing I/O [ 103.827337] nvme1n1p4: writeback error on inode 67250623, offset 90112, sector 59489176 [ 103.827342] block nvme1n1: no available path - failing I/O [ 103.827346] nvme1n1p4: writeback error on inode 67250623, offset 94208, sector 59489184 [ 103.832144] XFS (nvme1n1p2): Block device removal (0x20) detected at fs_bdev_mark_dead+0x43/0x60 (fs/xfs/xfs_super.c:1179).

[ 103.832207] XFS (nvme1n1p4): Please unmount the filesystem and rectify the problem(s).
Would it be possible for nvme-cli to prevent this from occurring or to present a warning to the end user?
