Hi everyone,<br>
<br>
<br>
I have been running an Edgy fileserver for about 6 months now. When I
came home from work last week I found my files all inaccessible. After
investigation I found issues with my PV. I would like to recover my
data and replace the drives if possible any help is greatly appreciated!<br>
<br>
I have one system drive and 6 storage drive, all raid1. The storage layout is<br>
2x160GB /dev/md0<br>
2x250GB /dev/md1<br>
2x250GB /dev/md2<br>
After investigation I found problems with my lvm. pvdisplay showed: <br>
Couldn't find device with uuid 'xjWU5M-G3WB-tZjB-Tyrk-Q7rN-Yide-1FEVh3'.<br>
<br>I ran the command:<br>
sudo pvcreate --uuid "xjWU5M-G3WB-tZjB-Tyrk-Q7rN-Yide-1FEVh3" --restorefile /etc/lvm/archive/fileserver_00006.vg /dev/md2<br>
<br>
This seemed to recover /dev/md2. I re-ran pvdisplay and got<br>
Couldn't find device with uuid '1ATm8s-oxKG-nz0p-z1QA-a0s4-od9T-AMZRoo'.<br>
<br>
I figured I could run the same command on md1,<br>
sudo pvcreate --uuid "1ATm8s-oxKG-nz0p-z1QA-a0s4-od9T-AMZRoo" --restorefile /etc/lvm/archive/fileserver_00006.vg /dev/md1<br>
<br>
and got the message:<br>
Couldn't find device with uuid '1ATm8s-oxKG-nz0p-z1QA-a0s4-od9T-AMZRoo'.<br>
Device /dev/md1 not found (or ignored by filtering).<br>
<br>After re-executing the above command with -vvv at the bottom of the output I get the following message: <br>#device/dev-io.c:439 Opened /dev/md1 RO<br>#device/dev-io.c:264 /dev/md1: size is 0 sectors<br>
#filters/filter.c:106 /dev/md1: Skipping: Too small to hold a PV<br>#device/dev-io.c:485 Closed /dev/md1<br>#pvcreate.c:81 Device /dev/md1 not found (or ignored by filtering).<br><br>
Here is my pvdisplay. Again, any help is Greatly appreciated<br>
