+ | ==== Resync Data ==== | ||
+ | |||
+ | Testing out fail over and deletion of data on secondary then a full resync process: | ||
+ | |||
+ | |||
+ | * started a full --resyncstorage --mirrorgroupid=101 --timestamp=0 | ||
+ | * got --getentryinfo EntryID for a file in my / | ||
+ | * did a cat / | ||
+ | * brought primary storage down | ||
+ | * redid the cat above (it hangs for a couple of minutes, then displays the file content) | ||
+ | * while primary down, I ran rm -rf / | ||
+ | * a cat now generates the expected file not found error | ||
+ | * brought up primary and started a full --resyncstorage --mirrorgroupid=101 --timestamp=0 | ||
+ | * the nr of files and dirs discovered is as expected lower by the correct values | ||
+ | * when I now search for the EntryIDs obtained before they are gone from / | ||
+ | |||
+ | Nice that it works. | ||
