What am I supposed to do when a sata cable disconnects and reconnects as
another device?
I had a disk at probably /dev/sda.
At a certain point the filesystem had become read-only. I realized the
cable must have disconnected and after fixing it the same device was now
at /dev/sdf.
Now the device had gone missing from the system but it would not refind
it.
# pvscan
WARNING: Device for PV fEGbBn-tbIp-rL7y-m22b-1rQh-r9i5-Qwlqz7 not
found or rejected by a filter.
PV unknown device VG xenpc1 lvm2 [600,00 GiB /
158,51 GiB free]
pvck clearly found it and lvmdiskscan also found it. Nothing happened
until I did pvscan --cache /dev/sdf:
# pvscan --cache /dev/sdf
# vgscan
Reading all physical volumes. This may take a while...
Duplicate of PV fEGbBn-tbIp-rL7y-m22b-1rQh-r9i5-Qwlqz7 dev /dev/sdf
exists on unknown device 8:0
Found volume group "xenpc1" using metadata type lvm2
Now I was able to activate it again and it was no longer flagged as
partial (but now it is duplicate).
The unknown device 8:0 is clearly going to be /dev/sda, which is no
longer there.
How can I dump this reference to 8:0 or should something else be done?
Oh right.... pvscan --cache without a parameter....
I wonder if I can run this while the thing is still activated....
I was beginning to think there'd be some hidden filter rule, but it was
"just" the cache.
Should this thing be automatically resolved? Is running pvscan --cache
enough?
