Allow for '-o feature@=disabled' on the command line

2016-10-25T23:17:47Z

Sometimes it is desirable to specifically disable one or several features directly on the 'zpool create' command line. $ zpool create -o feature@=disabled ... Original-patch-by: Turbo Fredriksson Reviewed-by: Brian Behlendorf Signed-off-by: loli10K Closes #3460 Closes #5142 Closes #5324

Turn on/off enclosure slot fault LED even when disk isn't present

2016-10-24T17:45:59Z

Previously when a drive faulted, the statechange-led.sh script would lookup the drive's LED sysfs entry in /sys/block/sd*/device/enclosure_device, and turn it on. During testing we noticed that if you pulled out a drive, or if the drive was so badly broken that it no longer appeared to Linux, that the /sys/block/sd* path would be removed, and the script could not lookup the LED entry. To fix this, this patch looks up the disks's more persistent "/sys/class/enclosure/X:X:X:X/Slot N" LED sysfs path at pool import. It then passes that path to the statechange-led script to use, rather than having the script look it up on the fly. This allows the script to turn on/off the slot LEDs even when the drive is missing.

Fletcher4 algorithm implemented in pure NEON for Aarch64 / ARMv8 64 bits

2016-10-21T17:55:49Z

This is not useful on micro-architecture with a weak NEON implementation (only 64 bits); the native version is slower & the byteswap barely faster than scalar. On A53 or A57, it's a small improvement on scalar but OK for byteswap.

Multipath autoreplace, control enclosure LEDs, event rate limiting

2016-10-19T19:55:59Z

1. Enable multipath autoreplace support for FMA. This extends FMA autoreplace to work with multipath disks. This requires libdevmapper to be installed at build time. 2. Turn on/off fault LEDs when VDEVs become degraded/faulted/online Set ZED_USE_ENCLOSURE_LEDS=1 in zed.rc to have ZED turn on/off the enclosure LED for a drive when a drive becomes FAULTED/DEGRADED. Your enclosure must be supported by the Linux SES driver for this to work. The enclosure LED scripts work for multipath devices as well. The scripts will clear the LED when the fault is cleared. 3. Rate limit ZIO delay and checksum events so as not to flood ZED ZIO delay and checksum events are rate limited to 5/sec in the zfs module.
