Sorry, accidently sent the previous message before completing the compose. :-(
What is the difference between JOURNAL_MAX_TRANS_AGE and JOURNAL_MAX_COMMIT_AGE
defined in reiserfs_fs.h ?
I see that both are set to 30 as default. Would reducing the either of
them to lower
values give more persistency in filesystem operations in post-crash scenarios ?
What are the side-effects of changing these values ?
Thanks,
Ash

Reducing JOURNAL_MAX_TRANS_AGE should cause transactions to flush
earlier. Once a transaction is flushed - it will be replaied on
post-crash reboot.
