Public bug reported:
Hi,
The last week I've had several times a system freeze when performing
disk-intensive operations.
today on several 'cp' commands, two times a freeze (one with 5 cp-commands
running, other with 4 cp-commands running)
a couple of day's ago while resizing an ext4 filesystem (from 1.3T down to 590G
using resize2fs)
For the last freeze I took pictures, no log can be found on the disk, or
at least not that I know of.
I'm using the machine for kvm hypervisor, but I do not suspect that to
be a problem (running only simple kvm's at the time with virtio, amd-d).
I suspect problems in the kernel area, since problems show while using
basic commands.
The system freezes up totally, unreacheable over the network, keyboard attached
is also not responding.
Only a reset can be performed.
I cannot tell copy commands were running at the time of freezes.
I can tell resize2fs command did not complete at that freeze (so it wat running
at the time).
