RE: Software encryption at fscrypt causing the filesystem access unresponsive

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Ted,

I don't see fast_commit feature is enabled for this filesystem.

Here are the filesystem features enabled for that disk partition,

Filesystem features: 
has_journal ext_attr resize_inode dir_index stable_inodes filetype needs_recovery extent 64bit flex_bg encrypt sparse_super large_file huge_file dir_nlink extra_isize metadata_csum

Thanks,
Yuvaraj.

The stack trace seems to indicate that the fast_commit feature is enabled.  That's a relatively new feature; can you replicate the hang without fast_commit being enabled?
