disk failure - replacement questions


alexwick

Question

So i had a disk fail a while ago (3TB)... I really havnt paid to much attention to DP in the last year. it was just running more or less...

Since the drive was failing, i removed it from the pool and it started measuring. (still doing it as i type this)

Now after it's done i plan to add the new drive (8TB). )or should I do that right now?

 

My question is in there a LOG that I can see somewhere when the last successful file duplication check was?
Just making sure i haven't lost anything. WIth 10TB complete pool it's hard to see by just checking through the files...

ALSO

2nd question. before i always filled up the pool and added 2 same size dirves (2 times 2 TB 2 times 3 TB ) etc.... now i want to replace some older drives, after the one that crashed is reduplicated.

What is the best way to do this? One at a time? (like the older 2TB drives the have at least started as original and / backup) I am afraid if i take more then one out i might take a original AND a backup out at the same time.... but ideally the oldest 2 TB need to be replaced as well.

Thank 

Alex

Either is fine, but I would put the drive in right away.  That way, if it needs to duplicate data, it will most likely place that on the 8TB drive.

The service logs may show that, but StableBit DrivePool doesn't maintain a list of the files in the pool.   There are some guides to do this manually, though.

As long as you're removing the drive via the UI first, there should be absolutely no issues.

Remove a drive, pull it, replace it and add it to the pool.
