Upgrade (make visible) Snapshots in a ReadyNAS, and Delete Them
article #1147, updated 19 days ago

When ReadyNAS firmware is upgraded, snapshots can become invisible, losing much space. To fix that:

  1. Turn on SSH, in System / Settings / Services.
  2. Using putty, SSH to root@nas , where “nas” is the IP of the NAS, using the admin password.
  3. Do this:
touch /.force_snapshots_upgrade
systemctl restart readynasd
  1. The GUI will report upgrade in progress. Wait for it.
  2. We have now fixed it so we can do things to the snapshots. Let’s make them visible in the filesystem. Browse to Shares, click on the share name (often Backup), click the gear icon on the right, and check Allow Snapshot Access, Apply and OK.
  3. We can now see them at \\NAS\Backup\snapshots. If we create a blank directory on the Windows server’s hard drive, say C:\B, and do the following, we will wipe all of the snapshots on that share and begin recovery of all of the space:
    ROBOCOPY C:\B \\NAS\Backup\snapshots /MIR /R:1 /W:1
    Full recovery of the space actually takes a bit more, there are automatic elements which initiate after the above is done, and also after the next step is done.
  4. Then we run a Balance operation which Netgear recommends. Browse to System, then Volumes, and then click the Gear icon inside the NAS object, and choose Balance. This will take a while, and more space will be recovered. A weekly Scrub and Balance are both recommended. Scrub actually takes longer.

Bicycle Derailleur Adjustments
article #1130, updated 66 days ago

If you bicycle much using the most common shifting systems, you’ll need these. Thus far I am finding the instructions on Liv’s Cycling to be best for the rear, and wikihow or madegood.org for the front. The most important thing yet learned: instructions often get the “H” and the “L” limit screws reversed for whichever bicycle you’re on. Got to check it for each derailleur, by seeing the slight movement per half-turn of each screw. General thoughts:

  1. Mounting position has to be right. This is not very confusing in the various web resources studied.
  2. Each derailleur, front and rear, has an H screw and an L screw. On each, one screw sets the max deflection towards the frame, the other sets the max deflection away from the frame. These are called limit screws.
  3. Cable tension can simulate one of the limit screws. Use the tension caps on the gear control, or (when they are there) the caps on the derailleurs themselves, to relieve tension, to verify that you are seeing reality of limit screws, not the simulation of the cable tension :-) Which screw tension simulates, also varies by make and model and type of derailleur.

BBQ sauce with no added sugar
article #1116, updated 114 days ago

This is “Cornell Chicken Barbecue Sauce”, created in 1950 by Robert C. Baker in order to encourage certain kinds of agriculture, especially that of chicken. The sauce remains extremely popular in certain places. And it has no added sugar, unlike every BBQ sauce this writer has ever seen in many supermarkets.

1 cup cooking oil
1 pint cider vinegar
3 tablespoons salt
1 tablespoon poultry seasoning
1/2 teaspoon pepper
1 egg

Beat the egg, then add the oil and beat again. Add other ingredients and stir. The recipe can be varied to suit individual tastes. Leftover sauce can be stored in a glass jar in a refrigerator for several weeks.

Very simple machines this time: suspenders
article #912, updated 757 days ago

This post is not for all or even most, certainly :-) But if you want suspenders which snap onto belt loops, rather than the usual variations on alligator clips or buttons, they really exist and work very well, from here:
