Speeding up internal Hard drive mount
Over on this thread http://www.linuxquestions.org/questi...es-4175549373/ I was helped to see what was causing slow boot. Right now I'm just under 3 minutes to boot. One of the biggest culprits is my /home hard drive which takes 37 seconds to mount.
The hard drive is btrfs, SATA III, and 3TB. What could be making it take so long? What could I do to improve it? Thanks! |
Hardwareinfo?

How long does the drive take to spin up? That could be a big problem right there.

It should be in the SMART data of the drive. gnome-disks can tell you that.
EDIT: Added a screenshot of my old 1TB drive's SMART data. If the assessment of the spinup time is not OK, then you should probably look into getting a new drive. |

I'm sorry, I don't think I was clear enough. The SMART data is accessible through the menu in gnome-disks, as in the picture I attached.
Code:
3 Spin_Up_Time 0x0027 183 179 021 Pre-fail Always - 5850 |
Well, for Pre-Fail, you want to be above the number. But I wouldn't put too much stock into it. Here's another drive that is the same size with btrfs:
Code:
# smartctl -a /dev/sdc |
Hmm, as I look through this - IF the SMART data is accurate ... my home drive is a 5400 RPM drive. Perhaps that's the big culprit? A 5400 RPM drive with nearly 3TB of data.
|
It is unusual that mounting takes 37s.

Yeah, I *THINK* it's the type of drive. I think WD has some tuning on it that makes it load up more slowly because it's meant to go into Tivos or something like that
|
That might explain the subpar 5400 RPM, but not the 37 second mount time. I've never really delt with DVRs, but I would imagine that 37 secs is a little long to be waiting even for a DVR.
|
Yeah, although they're not meant to be turned off. My tablet takes forever to reboot. But most of the time it's instant on.
|
How long has the drive been like this?
|
As far as I know - always
|
Either you have a failing harddrive, or its just that slow. If it were me, I'd get a new one regardless. Your boot times are ridiculous.
I highly recommend the WD Black. |
