PVS output not showing drive
Clash Royale CLAN TAG#URR8PPP
I had created physical volume earlier i.e. /backup, /ndasdb, /processor, /latro.
Don't know what exactly happened, but /ndasdb is not showing in any of this output result:
Pvdisplay, Vgdisplay, and lvdisplay. rest 3 are showing.
I can see the lun in multipath -ll (ndasdb is there)
I tried to recreate it with pvcreate /dev/mapper/ndasdb but its gives me this error:
WARNING: gfs2 signature detected on /dev/mapper/ndasdb at offset 65536. Wipe it? [y/n]: n
Aborted wiping of gfs2.
1 existing signature left on the device.
Is it true if I do yes it will delete my all data?
Is there anyway to bring my drive back without loosing any data?

Is it true if do yes will delete my all data?
Yes, you are right because you will write LVM data inside the disk.
is there anyway to bring my drive back without loosing any data.
As pvcreate command detected a GFS2 filesystem intact in the disk and assuming it can be mounted, you can proceed as follows:
- Create a mount point and a backup folder:
mkdir /mnt/mountpoint,backup - Mount the disk:
mount -t gfs2 /dev/mapper/mdasdb /mnt/mountpoint - Copy the data in
/mnt/mountpointfolder to/mnt/backup:cp -r /mnt/mountpoint/ /mnt/backup/ - Now your data should be in
/mnt/backupfolder.
I hope this helps.
