The warning is somewhat inconsequential... you can upgrade the pool to get newer features.

The criticals are your problem - your boot device is dying.. But, fortunately, the boot device isn't really a big deal to replace. Extract a complete configuration backup, replace the boot device (I presume you're using a USB flash drive... if so, consider moving to a small SSD - 40GB is sufficient - or, at minimum, get two USB devices and mirror them), reinstall FreeNAS, then restore the configuration.

Thanks for your reply....
I got some idea....OS is installed on 1TB SATA HD(boot device).
Now i am planing to connect a new 1TB SATA HD and fresh install FreeNas -11-STABLE on that, then i 'll restore the configuration.
Will it be fine and am i doing in a correct way.???
Extract a complete configuration backup from ->System->General->Save config (am i backing a correct config file.??)

Please confirm.

Many thanks,
Biswa

Doing it this way you are backing up the correct config file, yes.

BUT: As some people have reported problems with 11.1-RELEASE it might be the best to use either 9.10.2-U6 or 11.0-U4 for your fresh install and to wait with the upgrade to 11.1 until 11.1-U1 is out.

OS is installed on 1TB SATA HD(boot device).

Good Lord, why? A small flash device, or SSD of around 30 GB (up to no more than 120 GB) is plenty; anything more than that is a complete waste. But yes, the procedure you mention is correct.

This. You're wasting space and you're wasting energy. Find a nice little 40GB SSD... I've bought several Intel 320 series drives off eBay for $20... and use that.

Hello All,
Thanks for your valuable suggestions.
Now instead of 1 TB OS HD, I connected 200 GB SATA HD (currently 200 GB unused good HD available with me), installed OS and import confing file. Now its working fine with no critical alert.

Thanks again.
