FIRST I want to SAY thank you for everyone that has reached out.., great community i wasnt expecting so soon..
I have a linuxMint Small Form Factor PC (HP dc7600), i installed ZFS tools on it, using the
sudo apt-get install zfs command,
after that i plugged in the PNY USB stick into this system, first thing i did was
mkdir /tmp/freenas_usb then I ran the
lsblk command
to find the device, which was /dev/sdb so i issued the command
xdd if=/dev/sdb of=/tmp/freenas_usb/freenas8gb.img bs=64K status=progress
this made an exact image of the pny usb stick for backup purposes.
then I switched to root and then issued the
zpool import command
i was able to see the freenas-boot filesystem as well as the mike_volume , both showed online and no errors,
Code:
#root@:~ # zpool import
pool: freenas-boot
id: 14146660498753067820
state: ONLINE
status: Some supported features are not enabled on the pool.
action: The pool can be imported using its name or numeric identifier, though
some features will not be available without an explicit 'zpool upgrade'.
config:
freenas-boot ONLINE
gptid/ccf6de20-02b9-11f7-b31b-00185d01d640 ONLINE
then I issued the
Code:
#root@:~ # mkdir /tmp/freenas
#root@:~ # zpool import -R /tmp/freenas freenas-boot
then checked the status
Code:
#root@:~ # zpool status -v
pool: freenas-boot
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.
then i listed the zfs list
Code:
#root@:~ # zfs list
NAME USED AVAIL REFER MOUNTPOINT
freenas-boot 1.71G 7.6G 31K none
freenas-boot/ROOT 1.67G 7.6G 25K none
freenas-boot/ROOT/FreeNAS-9.3-STABLE-201702250051 4.46M 7.6G 515M /tmp/freenas
freenas-boot/ROOT/FreeNAS-9.3-STABLE-201702160044 5.55M 7.6G 517M /tmp/freenas
freenas-boot/ROOT/FreeNAS-9.3-STABLE-201702282017 1.66G 7.6G 517M /tmp/freenas
freenas-boot/ROOT/Initial-Install 1K 7.6G 507M legacy
freenas-boot/ROOT/Wizard-2017-02-25_05:05:54 1K 7.6G 507M legacy
freenas-boot/ROOT/Wizard-2017-02-25_05:27:47 1K 7.6G 507M legacy
freenas-boot/ROOT/default 504K 7.6G 508M legacy
freenas-boot/grub 27.2M 7.6G 6.80M legacy
then I ran
Code:
#root@:~ # zfs get all
#root@:~ # zfs get all freenas-boot/ROOT/FreeNAS-9.3-STABLE-201702282017
so then i ran
Code:
#root@:~ # zfs mount freenas-boot/ROOT/FreeNAS-9.3-STABLE-201509282017
#root@:~ # ls /tmp/freenas
.cshrc .profile .rnd COPYRIGHT bin
boot cfg conf data dev
entropy etc home lib libexec
media mnt nonexistent proc rescue
root sbin sys tmp usr
var
so now I can see the /data folder
so I then i attempted to save the /data folder and files
Code:
#root@:~ # mkdir /tmp/recover
#root@:~ # mount -t ext2fs /dev/da1s1 /tmp/recover
#root@:~ # cp -R /tmp/freenas/data /tmp/recover/
#read fail /tmp/freenas/data/freenas-v1.db
#
i received read errors on the freenas-v1.db file,, YEP THE DATABASE file that is FreeNAS configuration..
so after reading all your comments I tried few things..
1. i downloaded the 9.10.2-u5 iso (thank you garm! and redcoat)
2. i burned it to a disk and booted my linuxmint machine to that disk
3. i did a install/upgrade onto the existing pny usb stick, and told it do upgrade the same version (did not format)
3a this said i would keep the database intact and upgrade and put the database back when complete.
4. after the upgrade was complete i shut down that linuxmint system and moved the pny usb stick into the NAS server.
This time it got further, passing through the countdown and onto most of the visual items you see during bootup.. however
it said it was runaway on /tty0 and i could see massive amount of script errors py.xxxxx or py.yyyyy just all kinds of trash I didnt understand
but knew i never seen it before during boot.
so back to the linuxmint system
1. boot cd insert NEW USB stick (16GB)
2. install/upgrade to new stick
3. complete install (FORMAT)
4. after the fresh install complete, shut down the linuxmint system and moved the NEW usb stick to the nas server.
THIS TIME!!
it booted all the way up.. to a normal prompt, with of course a new IP..
accessing the new IP via webpage, i couldnt figure out where to change the IP , so back to the console and did it that way.
changing bge1 to the static ip that i wanted..
importing ... well i was confused on which to do, import disk or import volume, first i tried disks, as it said 5TB
however it was asking me what filesystem and zfs was not one of them.. so i knew that was wrong..
so i exited that and chose import volume, this time it asked encrypted zfs or not ? mine was not, it said importing...
once it completed i could see all the volumes , WOW! THEY ARE THERE!!!!!!
so i started the SMB service and pointed to the SMB share i had created before and was able to see my data!!!!!!!!!!!!!!
OMG!! i was so gitty HELL YA , this is cool. there is my data i was so scared i had lost.. turns on the ZFS is pretty stable, yet the usb
isnt to be trusted.
so now its a matter of configuring the ftp and trying to remember the jails and nextcloud way i did things, needless to say, i have already made a backup config file onto my current PC.. i have searched and searched but cannot find the db file backup i did months ago. so i am ass out with
just having to reconfigure.. which is ok, ill accept that. I will also invest on a 4 or 6TB USB drive as a backup to my backups. :)
now i know about how powerful the dd command is, once configured i will use the dd command to make an image of the USB drive and have a spare USB stick on hand to image and have FreeNAS back up and running in a matter of moments. I think what ill end up doing is moving all the data over to the NEW USB 4-6TB drive and installing the newer FreeNAS 11 version and rebuild the pool and shares, ftp, etc.. I cannot seem to find anything that says i can do a direct upgrade from 9.10.2 to 11.x
AGAIN! Thank you all for your help and having me take a deep breath i needed that.
