Subject: Performance Testing MD-RAID10 with 1 failed drive
Date: Thu, 20 Oct 2022 01:00:15 +0530	[thread overview]
Message-ID: <CAEQ-dADdRd91GBkTzVU0AQiXQ4tLitYsU2uLziWOi=hLtaBK0w@mail.gmail.com> (raw)

Hello all,

We run Linux RAID 10 in our production with 8 SAS HDDs 7200RPM.
We recently got to know from the application owners that the writes on
these machines get affected when there is one failed drive in this
RAID10 setup, but unfortunately we do not have much data around to
prove this and exactly replicate this in production.

Wanted to know from the people of this mailing list if they have ever
come across any such issues.
Theoretically as per my understanding a RAID10 with even a failed
drive should be able to handle all the production traffic without any
issues. Please let me know if my understanding of this is correct or
not.

Also if anyone can help with some links/guides/how-tos about this
would be great.

Thanks,
Umang Agarwalla
