Subject: Re: Removing a failed device from LVM2/DM

The vgreduce --removemissing helped a lot, thanks! But I still remain
with all these error messages about the removed device. I tried
everything again - using devices sda, sdab & sdad (failing sdab), and
now every time I issue an LVM2/DM command I get all sorts of error
messages about /dev/sdab failures. The 'pvs -a -o +devices' command not
only puts out a ton - but also has a messed up display about the devices
left working:
# pvs -a -o +devices

/dev/sdad vg lvm2 a- 271.34G 271.34G
Why the 5 lines for 2 devices?
I've attached a log of commands & results.
I have tried adding in "/dev/sdab" as being filtered out
in /etc/lvm/lvm.conf but that doesn't change things. Here is first part
of the output from lvm dumpconfig:
# lvm dumpconfig
devices {
dir="/dev"
scan="/dev"
preferred_names=[]
filter=["r|sdab|", "a/.*/"]
cache_dir="/etc/lvm/cache"
cache_file_prefix=""
write_cache_state=1
sysfs_scan=1
md_component_detection=1
md_chunk_alignment=1
ignore_suspended_devices=0
}
but commands still error on /dev/sdab:
# lvs
/dev/sdab: read failed after 0 of 2048 at 0: Input/output error
LV VG Attr LSize Origin Snap% Move Log Copy% Convert
lv vg mwi-a- 32.00G lv_mlog 100.00
So, how do I stop LVM2/DM from "looking at" /dev/sdab?
Thanks,
Alan
