Subject: NVM and swap device
Date: Tue, 12 Jan 2016 19:40:30 -0800 [thread overview]
Message-ID: <20160112194030.5b74ecdc@xeon-e3> (raw)
I have a nice shiny new Intel NVM PCI card; decided to use it for a filesystem and swap.
The filesystem (btrfs) is doing fine, but the swap device was throwing occasional
random errors. Suspect a driver problem rather than hardware.
I am using 4.4 kernel without patches.

The swap device was being added via /etc/fstab by UUID.
I gave up and went back to spinning rust for swap device for stabilty.
Device partitions are:
Disk /dev/nvme0n1: 781422768 sectors, 372.6 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 304117A4-18EF-4B51-92F4-8015758B5CB0
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 781422734
Partitions will be aligned on 8-sector boundaries
Total free space is 0 sectors (0 bytes)
Number Start (sector) End (sector) Size Code Name
1 34 2047 1007.0 KiB EF02 BIOS boot partition
2 2048 33556479 16.0 GiB 8200 Linux swap
3 33556480 781422734 356.6 GiB 8300 Linux filesystem
