Hey all,
last night we had some major nightmare when we wanted to resize some LVM
partitions for regular maintenance. Somehow the Linux kernel on that datacenter
server would simply not show the lvm volumes anymore _at all_.
I have never seen something like that ever, and I have absolutely no idea how
that could happen. Well, ok, there could be some typo, bug in the Linux kernel.
But not showing any LVM data in /proc and /sys and the general commands?
And the LVM partitions where still mounted, and running, …
Very, very strange.
Early this morning we rebooted that server which brought the LVM reports back,
like:
# pvdisplay
--- Physical volume ---
PV Name /dev/md0
VG Name lvm0
PV Size 683.73 GiB /
…
# lvdisplay
--- Logical volume ---
LV Path /dev/lvm0/srv
LV Name srv
VG Name lvm0
…
As mentioned before, yesterday all this commands simply yielded nothing, …
Unfortunately the reboot brought the filesystems back vastly corrupt, we
restored the general http services and will now also restore that mass download
VM, which is currently surviving corrupted files.
Again, this is all quite strange, never seen, and a bit untypical for a bad
storage sector (this is RAID1), flipped RAM bit, or simply a Linux typo. Which
brings me to the latest NSA disclosures: One can not trust anything anymore,
unfortunately could also been some secret agency.
Thanks god this are all just public http files, so, … we are just restoring,
keep and eye open and let us know when you notify anything, …
