Topic: Unusual Process mdrecoveryd

[cc_skavenger]

Hello all,

I have a server that is showing this in top:

10 root   18446744073709551615 -20   0  0  0 SW<  0.0  0.0   0:00   0 mdrecoveryd

Does anyone know what is going on?  The server only has one hard drive in it, so why is mdrecoveryd running?

TIA

Hi Marco,

mdrecoveryd is a kernel process.
It shouldn't be using any resources if you don't have RAID configured, but it will still run because RAID is configured in most kernels, incl. the RH kernel SME uses, by default.

Nice value you report is strange, it should be between 20 and -20.
The higher boundary seems to have "flipped" in your case.
That however isn't all that unusual it seems.
It has been reported for RH 7.2, 7.3 kernels.
A little googling will bring examples like this.

I am afraid I can't help you in what went wrong,
but the only way you can get rid of mdrecoveryd is recompling a new kernel   -

Regards
Reinhold

ok, just making sure.  I want to reboot this server, I am having problems with it, but I was thinking that it might not come back up.  It is about 250~275 miles away

Thanks
