Regarding integck failure

[Sharma, Abhishek (A.)]

Hi All,

I am running the integck test on a UBIFS file system with power cut enabled.
Below steps were followed:

1. enabling the power cut after every minute using echo 1 > /sys/kernel/debug/ubifs/ubi2_0/tst_recovery
2. run the integck with -p option. (integck -p /meta  where meta is a UBIFS partition)

After around 4 hours the integck stops with the following error message

UBIFS error (pid 594): ubifs_scan: bad node

Please let me know if it is a valid failure or I am missing something.
