Thinkpad X1 Carbon (5th Gen, 2017) – Touchpad behaviour changed / degraded a few days ago

Drag-and-drop (e.g. for selecting sth) is not acting as before; fear some (automatic) update might have messed it up. Any ideas how to fix / trouble-shoot / work-around? Really irritating…


Further details:

  1. Same (new/irritating) behaviour in Win10-Guest in VirtualBox.
  2. Old behaviour: Could physically “click” / “depress” the corner of the
    touchpad with one finger and “drag” with another finger to select
    (“drag-and-drop”).
  3. New behaviour: Can (double-)”tap” (but not
    (de-)press) to click-and-drag to select.
  4. Also: Reverts to old
    behaviour every so often but not reliably (making the experience
    even worse).
  5. This not only pertains to “selecting” sth but also drag-and-dropping / moving windows. Very cumbersome. This cannot be intended behaviour; therefore I am inclined to think this is some kind of bug / regression.

Settings (unchanged):

ZFS pool degraded on reboot

I have a Ubuntu server set up with a 14-disk ZFS raidz2 pool.

About 80% of the time, on reboot, I will end up with a degraded pool with two of the disks marked as faulted. The drives that are faulted aren’t always the same, but it is always exactly two drives. For example:

$ sudo zpool status
  pool: tank
 state: DEGRADED
status: One or more devices could not be used because the label is missing or
        invalid.  Sufficient replicas exist for the pool to continue
        functioning in a degraded state.
action: Replace the device using 'zpool replace'.

errors: No known data errors

I can export and re-import the pool, and the disks are no longer faulted. For example:

$ sudo zpool export tank
$ sudo zpool import tank
$ sudo zpool status
  pool: tank
 state: ONLINE
status: One or more devices has experienced an unrecoverable error.  An
        attempt was made to correct the error.  Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
        using 'zpool clear' or replace the device with 'zpool replace'.

The HBA being used has worked correctly in another server.

Anything else I can try to avoid these faulted drives on reboot? I have another HBA I could swap in.

Search Index degraded, index reset never completes

I cannot for the life of me get search services running on a new server.

When I open up the service administration web panel for search it shows a yellow exclamation mark on the Index.

PS> Get-SPEnterpriseSearchStatus -SearchApplication $ssa -Detailed -Text
Name      : IndexComponent1
State     : Degraded

Steps done so far (they didn’t help):

  • Cleared the SP Config cache (https://social.technet.microsoft.com/Forums/sharepoint/en-US/ede11fc6-59a7-47be-893d-dc1ea4c88879/cant-reset-index-sharepoint-2013). Everything seems normal after restarting the SP timer service, the XML files are recreated and config.ini goes back to the same integer as before.
  • Deleted the SP index data (http://blogs.msdn.com/b/kristopherloranger/archive/2014/09/26/sharepoint-2013-on-prem-reset-index-stuck-resolution.aspx). I can see that it recreates the store after starting the search service again, so it would appear that permissions are working.
  • Initiated a index reset through the central administration (sits at “We’re working on it” until it times out. Done the same thing through PowerShell and it just sits there for an hour without giving any error mesages).

After trying the steps above the search status is “Paused for:External request, Index reset”. The pause was initiated when the database(s) were renamed as per the technet article. The index reset was initiated by me.

I have tried using ULSViewer to dig further, but to be frank the output is a bit overwhelming.. I’m not really sure what to look for (or more specifically what to filter for).

Event log on the server seems normal. I can see informational messages about the index being reset, but never any messages about it completing the index reset. No idea if that should happen, either.

Environment details:

  • New 2012 R2 + SP 2013 installation
  • Different logical disk for search data
  • Databases are hosted on a remote SQL 2014 server and renamed to avoid GUID’s
