Have you tried xfs?

Thanks for answering,
My filesystem would be 15 TB < 16 TB.
GFS also crashed and burned so are you sure that this
this is a problem with ext4?
Would Fedora and newer kernel be better?
On my tests the crashing filesystem was 7TB.
When I added a second fs of 2 TB on lvm, so total > 8TB
I had the crash.
I did a new test now and didn't use GFT partitions
but the whole physical/logical drives
sdb -
| ---> md0 ---> LVM ---> ext4 filesystems
sdc -
all sdb, sdc, md0 are gpt labeled without gpt partitions
inside. No crash so far but without any data written.
Maybe the gpt partitions did the bad thing?
Can md0 use large gpt drives with no partitions?
can lvm2 use large raid device with no partition pv?
I could try XFS but i'm not familiar with it,
so I wouldn't know the optimized values for
such a large fs

Giannis
