If / dev / sdb2 is not found or is being ignored due to a filter error, this guide is here to help you.

 

 

I am trying to add a volume of heavy physical work to add collections of volumes and therefore LV. Unfortunately I am getting the following error.

  [root @ server ~] # pvcreate / dev / sdb1The / dev / sdb1 device was not found (or filtered) by the user.[root @ server ~] # fdisk -l / dev / sdbWARNING: GPT (GUID Partition Table) found on '/ dev / sdb '! The fdisk utility does not support GPT.

I would be grateful for any help you can give me. This may be my first time I need to buy the primary, and while researching the post, I haven’t found anything that helped me that much before.

The MBR partition type is assumed to be “ ee “, which meansIt seems that our own hard disk may have a GPT partition table, but as a separate shows that there is more than one GPT table.

You should go straight to:
a) Use parted to create a GPT partition and use that partition as a specific PV
b) Completely remove the partition table from the MBR part and just use the block accessor / dev / sdb as PV

I found that I needed to both restart the server and run “partprobe / dev / sdaX” in order for pvcreate to be properly informed about the partition.

Also, fdisk doesn’t know anything about lvm, so Will was throwing partition errors, which I think was a big hurdle when we weren’t always like this.

  partprobepartprobe / dev / sdb 

  pvcreate / dev / sdb1 

Note. Sometimes the whole family has to manually update the kernel. This is why the above command is required.

The type of filtering device can also be critical. If you run pvcreate with -vvvv combined with an error like “Ignore: unknown device type LVM 251”, you need to add the magic number to the entire list of allowed devices. …

Just find the app, enter the number in / proc / devices , then add it to the devices provided with lvm config. / etc / is connected to lvm / lvm.conf , for example:

Your shared writers don’t have sections, which means that / dev / sdb1 doesn’t exist. First you need to create a main section.
