The following process will lead TNC to find no corresponding inode nodePlease help me to understand what exactly is going on.
(Reproduce method see Link):
1. Garbage collection.At this point all valid nodes are written to LEB B, right?
1) move valid inode nodes from leb A to leb B
(The leb number of B has been written as GC type bud node in log)
2) unmap leb A, and corresponding peb is erased
(GCed inode nodes exist only on leb B)
I mean, the uncorrectable ECC error is caused by hardware which may lead to corrupted nodes detected in UBIFS. I found uncorretable ECC errors on my NAND, in the environment of high temperature and humidity.
2. Poweroff. A node near the end of the LEB is corrupted before powerIf writing nodes to B has finished, these pages should be stable.
on, which is uncorrectable error of ECC.
How can a power-cut affect the pages where these valid nodes sit?
