Does md_checker work on QuTS hero?

Does md_checker works on QuTS hero?
any references for SSH commanded regarding QuTS hero?

I tried running this command on my QuTS Hero TS-673A but the command returned to the prompt very quicky after running it. there maybe some other command that QuTS uses but I dont know it myself.

Command line options were also not available when tying in

md_checker --help

QuTS uses QNAP’s specific implementation of ZFS, but the core functionality is the same. Most commands are usable, such as pool status:

zpool status

https://man.freebsd.org/cgi/man.cgi?zpool

md_checker only displays data md devices, and as QuTS uses ZFS, it would not do much
QuTS still uses md RAIDs for the system (md9 and md13 and swap)

So you can see the system RAID via
cat /proc/mdstat
