Disk Temperatures

[jonheal]

I just upgraded to 9.2.0.1 (943) from a version of 9.1.0.1 from last July. My storage is on USB-connected disks. Suddenly, I can no longer see my disk's temperatures. This feature is not working with the new version. Is this functionality which will return with a future revision?

Hi jonheal,

Did you do 'Clear and Import' after upgrading to 9.2 ?

[jonheal]

I just tried that, and then I rebooted NAS4Free. Same result. No disk temperatures or serial numbers.

I have the four external USB disks connected to a hub which is then connected to my computer. I am running NAS4Free 9.2.0.1 (943) as a virtual machine using VMware Player, if that makes any difference.

USB connected disk is not recommended by N4F as storage pool, do you know risk?

USB disk only recomended for puntual data copy/read as backup, not as primary data pool.

As raulfg3 said, it is not recommended to use external USB disks.

However, as much as I am liberal towards virtualisation, it is a very bad practise to run NAS4Free on Type 2 hypervisor (e.g. VMWare Player), which is just another virtualisation software package that sits on top of another Host OS. Having so many layers between hardware and NAS4Free will cause unpredictable issue should unexpected event occurs ( Host OS goes to sleep/standby, unexpected reboot due to interrupted power supply, ? will happen when both Host OS and client OS ran heavily, causing resource contention ). Unless you are just testing water with NAS4Free, I strongly suggest you to move it off separate physical machine, or at most a Type 1 hypervisor such as VMWare ESXi (with VMDirectPath).

Having said that, I suspect yours are affected by the same issue that is just fixed. Would you mind to paste the <disk></disk> section within your config.xml so that I can further troubleshoot ?

[jonheal]

Well, I agree that having NAS4Free sitting on top of VMware Player sitting on top of Windows 7 is not the best of all worlds, but so far I've been okay. My computer doesn't sleep, and even when I've had an unexpected hard reboot, ripping the CPU out from under NAS4Free, journaling has kept everything intact, I reckon. When this happens, I run fsck for good measure and to reset the dirty flags. So far, CPU usage has been negligible as I really don't hit this system very hard.

As for "storage pool," I am not using ZFS, my disks are formatted as UFS, if that makes things any safer with external USB drives.

Bottom line, I can't get another computer right now, so I will have to keep muddling along as-is.

Anyway, the <disks> XML ...

The <disks></disks> xml you posted doesn't look lke you did a 'Clear and Import' at Disks|Management page after you restore your config file from 9.1 .

[jonheal]

I absolutely did a clear and import, but it made no difference. Please see attached.

After you do clear and import with rev 943, additional information will be added to the config file.

After you clicked 'clear and import', can you please backup your config from your NAS, and then copy and paste the <disks></disks> section here ?

Can you also do the following and paste the console output :

Code: Select all

smartctl -a /dev/da2
