Hello,
So today my pool of 2x4tb hard drives in mirror setup got filled up by an unexpected windows backup and another user. The root volume says 96% but every dataset within says 100%.
To top things off, while trying to delete some files, I've noticed some deletes are very slow and at least one of the drives is not sounding so good. At this point I'm nervous about best approach to safely get out of this mess.
I would very much appreciate some guidance here.
Current Knowns:
- FreeNAS-11.1-U6
- Motherboard has 4 SATA. 2 are used for the mirror, 1 for boot SSD, 1 for optical drive.
- Existing drives: 2 x 4tb Ironwolf NAS
- New drives: 2 x 8tb Exos Enterprise
- Deleted files manually over SMB to regain some space.
- Turned off snapshot tasks
- Rebooted to see if size updated after deletes. Startup took much longer than usual. Console showed importing pool and lots of drive activity. At least one of the existing drives do not sound so good... I don't think.
- Once startup completed, console just repeating: check_create_dir: mkdir ...... no space left on device
- Even though I've deleted some large files, GUI does not change from 100% on datasets.
- SMB service did not start on boot and will not start when clicking Start Now.
- Accessing and copying some files from FN to local system over SFTP seems normal... speed and sound wise.
- Some deletes are very slow and drive noise (not sure if bad or normal as usually case is closed and very quiet)
Current Unknown/Confirmed:
I've searched, and lots of the info for replacing drives seems to be for everything except simple 2 drives mirrored. I'm assuming that the process is similar?
- Offline a drive (the one making noticeably more noise than other) using the GUI
- Shut down and replace that old 4tb drive with a new 8tb drive
- Start system and use GUI to replace the now physically replaced offlined drive with the new drive.
- Wait for (hopefully) successful resilver
- If successful (best way to confirm?) then repeat these steps for the second old drive
Are above steps correct?
And to minimize risk and increase successful outcome, should I:
A: Use SFTP (since SMB not working all the sudden) and copy over files which are not yet backed up to a separate drive, and then attempt drive replacements? Or would this be decreasing my chances of a successful drive replace... maybe stressing an possibly failing drive?
B: Jump right into replacing drives one at a time using existing used sata ports.
C: Add one of the new drives on the cable that the optical drive is on, boot up and then replace a drive, shifting what cable each drive is currently connected to.
D: Unsure yet if this is possible or safe, but would be nice to move FN to a USB, disconnect optical, and add the 2 new drives as a new mirror. Can this be done?
Thank you in advance for your input.
