Ah sh!t!... erm... press on.

If you are reconfiguring a RAID, or whatever other storage system, and something unexpected happens, or something happens that you do not fully understand, stop.

Pressing on in this situation would likely make things worse. Pressing on for long enough will eventually make things irreversibly bad.

This thread on Tom's presents a good example. When reading it, keep in mind two things,

  • Even if one do not initialize the RAID, each time RAID 10 is reassembled and resynched with different order of disks, there is a 50:50 chance of total data loss

  • Repairing a filesystem or troubleshooting boot process without having fixed an underlying RAID first is certainly useless and often damages the data.
