Question 1

Is it safe to import a foreign config?

Accepted Answer

Sometimes. If the controller’s view matches the last healthy layout, import can be safe; if the metadata is from a different epoch...

Question 2

Can RAID 5 survive two failed drives?

Accepted Answer

Not in-place, but one “failed” drive often remains readable enough to reconstruct parity offline and recover data.

Question 3

Should I try a different controller or firmware?

Accepted Answer

Only after capturing the current metadata and drive states. Controller swaps can rewrite headers and commit the wrong layout.

Question 4

Why did power loss kill the array with no bad disks?

Accepted Answer

Write-cache + metadata epoch mismatch. The controller may distrust its layout; recoverable with the right sequence.

Question 5

How fast can I get a plan?

Accepted Answer

Same business day with logs and photos; we proceed without write risks.
