      Rudimentary TRIM support. · bdde40fe
      Mike Hibler authored
      We pass through a flag in the tmcd loadinfo call to tell whether to attempt
      to do a TRIM when loading the disk (or after loading the disk). If TRIM=1
      then we do so.
      Since it is not clear from what I have read whether repeated TRIMming is
      a detriment to SSD life, we throttle it as follows:
      1. We don't TRIM at all unless the sitevariable general/bootdisk_trim_interval
         is non zero. If it is set, we will wait at least that many seconds after
         the previous TRIM before we do it again.
      2. We keep track of the last trim via the node_attribute "bootdisk_lasttrim"
         which is a unix timestamp of the last time that tmcd responded to a
         loadinfo request in which it returned TRIM=1.
      2. We track, on a per-node basis, whether the boot disk should be TRIMmed
         or not. If the node or node-type attribute "bootdisk_trim" is non-zero,
         we will attempt a trim if the interval has passed since the last trim.
      So, we never trim if the sitevariable is 0 (the default value). If it is
      non-zero, we only trim the boot disk of those nodes that have the node or
      node_type attribute set and only after a sufficient interval has passed.
      This does not address non-boot disks, but currently frisbee won't mess
      with any other disk anyway. Eventually, we will have to have per-disk or
      per-disktype attributes if we want to do this better.

      Fix Linux MFS issue. · 254d0d6d
      Mike Hibler authored
      When locating the root device, if a BSD disk partition fills the entire
      DOS partition, then Linux will not create a separate /dev entry for it.
      In that case, we use the DOS partition device.
      Also, a couple of changes to resync with BSD slicefix.

      The latest in logic to have findSpareDisks not use the system disk. · 2eab9b24
      Mike Hibler authored
      If an available partition device (aka, the 4th partition on the system disk)
      represents less than 5% of the spare space we have found, ignore it.
      This will allow us to continue to use the 4th partition on the system
      disk of the d710s (450GB or so) and the second disk (250GB), but not use
      the 2nd partition (3GB), which would make us thrash about on the system
      disk even more than usual.
      Mostly this is for the new HP server boxes, so it doesn't pick up the 10GB
      left over on the (virtual) system disk when we have 21TB available on the
      second (virtual) disk.
      Another hack til blockstores rule the world...

      Rework client-side storage scripts to semi-coexist with mkextrafs uses. · 9cf8f9c6
      Mike Hibler authored
      Broke rc.storage into two phases, local blockstores and remote blockstores.
      Setup of the former will also pick a best candidate for an old-school
      "extrafs" and put the info in /var/emulab/boot/extrafs. This will be a
      single line with one of DISK=foo, PART=foo, or FS=foo depending on whether
      it found an available full disk, disk partition, or mounted filesystem
      that we can use for mkextrafs (in the first two cases) or where we can
      mooch off of (the last). This is only used in os_mountextrafs() right now;
      i.e., I have NOT changed the mkextrafs script. So explicit invocations
      by the user could still screw things up.
      I have tested this with local blockstores and a non-nfs experiment
      on both Linux and FreeBSD to make sure the most common sharing of space
      works. I have not made any new images and I have not yet tested to make
      sure I did not break non-blockstore, non-nfs experiments (i.e., where
      we really should run mkextrafs).
      So maybe don't make any new images til I get back, or else be prepared
      to clean up after me.

      Fix vlan interface handling under FreeNAS 9. · d403580d
      Kirk Webb authored
      FreeNAS 9 has reached a new level of broken in its handling of network
      configuration. Essentially each time a vlan interface is added, or
      IP configuration is added, it wipes all existing vlan configurtion
      and recreates it from its database.  Worse, when IP addresses/aliases
      are removed, it completely shuts off all network interfaces and
      re-configures them from scratch. ALL interfaces.  All of them.
      Every last one. Even those that are not in scope for the current
      modification operation.
      So, we now do ALL network manipulation, including create/destroy
      vlan operations, behind FreeNAS's back.  As a consequence, FreeNAS's
      UI will often not show the actual network configuration - it will only
      list those things that have been set up statically through its
      interfaces (command line or UI).
