It's concerning accessibility, not storage capacity. The RAID 5 array is likely down and needs to be repaired.

They became unavailable at a point... How would storage space stop you from accessing your files altogether?

It would make it so slow, and people are so impatient that we overload the computer with tasks to do that it's like I can't remember what all you wanted me to do. It's like you having chores. I know that if I don't do my chores one at a time, or if I don't have a written list that I can markout what is done, I'm like, "What all do I need to do?" I also will start something, but never finish it if I don't do one of the two things I said that I need to do in order to get my chores done.

I believe A is correct. As for the option of available storage space, that might cause write errors, but you would still be able to access the data on the drive.

I would check the RAID 5 array, then the available storage space.

It could either be that the RAID 5 array is down or the hard drive is full. If the hard drive is too full it would make it so slow, and people are so impatient that we overload the computer with tasks to do that it's like I can't remember what all you wanted me to do. It's like you having chores. I know that if I don't do my chores one at a time, or if I don't have a written list that I can markout what is done, I'm like, "What all do I need to do?"

Where in the question does it say RAID5? The question never establishes there was a RAID5 array setup in the first place. How can it be RAID5?

It's about understanding how RAID5 works vs regular storage. First the access was slowed because the array lost a disk. It limped on until another disk (probably the one picking up the slack) failed which caused the whole array to fail as RAID5 can only support 1 disk failure. If regular storage failed then files would have immediately been unavailable. If the drive was full then writing would be the issue, not drive failure. If fragmented then the access speed would suffer but it wouldn't cause failure.

This is not about a specific RAID type. The keywords here are access files "slower one week ago" and "unavailable today"

C is incorrect because if storage is full it does slow down access, but doesn't make it unavailable.

why can't just be a dying drive who slow down and actually die a week later?

Yes, I believe the answer should be worded as check the hard disk instead of storage space.

RAID 5 IS storage space. If the RAID 5 is failing then storage space is becoming unavailable. In my experience, disks do not slowly fail. They fail completely all at once. If a RAID-5 disk failed then the data would remain available via the parity bits, but I-O response time would be significantly degraded - all at once - not gradually. However, OVERALL available storage space - other than the RAID-5 - would affect I-O response time if the disk space was completely maxed out. The I-O control would be constantly busy trying to find available space and failing.

Option A is correct. Remember one of the advantage of RAID 5 is to provide fast access to files. So it means one or more of the RAID disk was failing and finally went making the files not accessible.

I believe it would be RAID 5 array because this is a sign that one of the drives is failing or has failed and needs replacement.

Shouldn't it be the available storage space?
