System Partitions Over Two Drives


I have a machine with two drives a Compact Flash card (CF) and a Solid State Drive (SSD). Recently I have been experiencing failures of both the SSD and the CF.

When I sent these back to the manufacturer for analysis, they reported that the SSDs and CDs are healthy - but that it appears that the partition table has become corrupt.

Using a Kickstart I created my Linux machine with the partitions split over the CF (to hold the operating system) and the SSD (to hold my data):

/ on the CF
/boot on the CD
/usr on the CF
/home on the SSD
Would Unix have an issue with using the CF to boot and run the operating system and using the SSD to store files?
Has anyone experienced any issues of this kind?

Welcome to LinuxQuestions.

Nope, having multiple drives of different types is not a problem. Can you provide some information on your hardware and distribution / version you are running?

Thanks.

It is a Fedora 12 operating system, using Apacer Solid State Drives and Compact Flash cards, running on an Advantech box.

For some reason, I'm seeing an increasing rate of failures - and the partition table becoming corrupt appears to be the issue.

Is that a typo? Fedora 12 vs 21?

What type of Advantech box? Embedded etc. What do you use the box for?

Nope - Fedora 12 (don't ask, I have to!)

Just wondering if there was possibly a boot issue?

I edited my post with another question.

It is a ARK 3202 box, and it is used for real time data capture and storage.

Are you sure it is just the MBR/partition table that is becoming corrupted?
How often does this happen?

You could save the good MBR via the dd command to a file and when the problem happens restore it to see if that fixes the problem.

Not enough information to know whether it is the hardware or your operating environment. Any power dropouts? Do you always perform an orderly shutdown?
