Removed HDD-2 from NAS (while running) and plugged into a Sharkoon USB-Bay and tried to recover data.
Tried to assemble all existing volumes:
% sudo mdadm --assemble --scan
mdadm: /dev/md/9 has been started with 1 drive (out of 24).
mdadm: /dev/md/256 has been started with 1 drive (out of 2).
This is a compiled list of falsehoods programmers tend to believe about working with time.
Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.
You can use ssacli (smart storage administrator command line interface) tool to manage any of supported HP Smart Array Controllers in your Proxmox host without need to reboot your server to access Smart Storage Administrator in BIOS. That means no host downtime when managing your storage.
CLI is not as convenient as GUI interface provided by BIOS or desktop utilities, but still allows you to fully manage your controller, physical disks and logical drives on the fly with no Proxmox host downtime.
ssacli replaces older hpssacli, but shares the same syntax and adds support for newer servers and controllers.
