Hi, today i had a strange crash of ALL nodes in parallel while running the 4.1 kernel. I was rebooting one node and all other nodes crashed with the following output: dlm: closing connection to node 5 BUG: unable to handle kernel NULL pointer dereference at 08e As there were no more

Re: [pve-devel] disabling transparent hugepage by default like kernel 2.6.32 ?

What about setting CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS = N? As I understand it, "not set" means "use the default setting the kernel devs think is the most sane for normal use", which in this case would be Y... On Wed, Sep 9, 2015, 06:58 Alexandre DERUMIER wrote: > >>I could

Re: [pve-devel] disabling transparent hugepage by default like kernel 2.6.32 ?

Hi, In my benchmarks, THP increase the memory transaction speed by 5-10% in the KVM guest if THP is activated on the host side, not in the VM side. I know that THP for databases is bad, but we are not using THP in the guest where the database lives. Can someone provide some benchmarks for that

Do you have tested it with a real workload and big memory ? (100-200GB for example). I'm curious to see what happen with a lot of alloc/desalloc and fragmentation. - Mail original - De: "Andreas Steinel" À: "aderumier" Cc: "Daniel Hunsaker"
