Disk usage discrepancy?

New accounts will be limited because they didn’t read the forum and did not try to use a search at least. If you pass this simple test - your account will not be limited.

The problem is widely discussed in this thread, so I moved yours another one thread here.

There are two (three) reasons:

  1. You have database related errors in your logs
  2. You have filewalker related errors in your logs
  3. You have both

Solution depends on what’s kind of error did you meet. If it’s a malformed, not a database, then you need to use these articles:

Both can be solved with the late article, but with a downside: the current stat and history will be lost. However, it wouldn’t affect the reputation and/or payout.

The second type of errors, related to a filewalker, can be solved by optimizing the filesystem, or by disabling a lazy mode.
The first is preferred, of course, however, the second one is an ultimate solution. In expense of the lost races of course.

Optimizing the filesystem includes:

  1. check and fix errors on the disk
  2. disable 8dot3 for NTFS: NTFS Disable 8dot3name
  3. disable atime (for NTFS: [Solved] Win10 20GB Ram Usage - #17 by arrogantrabbit), for Linux - please, use the search here or in the internet
  4. do a defragmentation if NTFS and enable the automatic defragmentation, if you disabled it (it’s enabled by default)
  5. Disable indexing (Windows only)
  6. Move databases to SSD (for Windows: Move databases on Windows storagenode - #2 by Alexey, for docker: How to move DB’s to SSD on Docker)
  7. If you have a managed UPS, enable the write cache (for Windows - in the disk volume Policy, you need to select both checkboxes)
  8. Add more RAM, if possible. Or add SSD cache before the disk subsystem (for Windows it’s possible too, but you need to use a tiered Storage).
