Hello,
I kept analysis of the problem which I reported previously and found how to fix
this problem.
(patch in my previou report is wrong.).
My understanding is there is a rule that blkno of JOP_FREEBLK or JOP_NEWBLK
must be the first
position in UFS block for each inode, for fsck_ffs's suj.c
Hello,
I think fsck_ffs has a bug in replaying partial frag truncate journal on UFS
SU+J.
Bellow I tested about the issue.
I tested blocksize==4KB, fragsize=512byte UFS SU+J. But I think these
parameters are not related to
this issue.
1) Preparing 4096byte(1block) test file.
2) Use "truncate"
Hello,
I'm testing UFS with SU+J. But it seems sometimes broken journal data has
written.
In softdep_process_journal (ffs_softdep.c), there is a while code to build
jsegrec and each entry.
But by my test, sometimes there is no entry then break this while code without
building jsegrec.
If this
