Extending a multipath'd /dev/mapper device that isn't listed as an LVM anywhere
Clash Royale CLAN TAG#URR8PPP
RHEL 5. I have a host that uses an EQL array for storage with multipath on the OS. I'm trying to extend the disk:
/dev/mapper/prdbkpp1 1.3T 1.3T 20G 99% /backup
I rescanned and resized via multipathd without issue. Correct size shown:
prdbkp (364ed2aa5a880392c6ef96415b8ed61e7) dm-16 EQLOGIC,100E-00
[size=1.5T][features=1 queue_if_no_path][hwhandler=0][rw]
_ round-robin 0 [prio=1][active]
_ 29:0:0:0 sdv 65:80 [active][ready]
_ 28:0:0:0 sdw 65:96 [active][ready]
_ 30:0:0:0 sdx 65:112 [active][ready]
_ 27:0:0:0 sdy 65:128 [active][ready]
Even though the device is listed as /dev/mapper/prdbkpp1, there is nothing under lvdisplay, vgdisplay, or pvdisplay that I can use to actually extend the LVM - nothing is listed but the OS LVMs that were in place originally. resize2FS doesn't do anything as you might imagine.
I'm very confused about how to actually extend this filesystem, then. Are we just extending the partition and resizing after the fact?
