[gentoo-user] Tuneing ext4 for reliability (not necessaryly speed)

[gentoo-user] Tuneing ext4 for reliability (not necessaryly speed)

[meino.cramer]

Hi,

for backup storage (see previous thread) I decided to use ext4. After
craling the net the reports I found about brtfs seemed to mixed to me.
If there are alternatives I overlooked...

I searched the net for answeres to the following question, but only
found outdated answeres...:

What options are recommended to set while initializing the filesystem
and later via tune2fs to increase the reliability of the filesystem?

Thank you very much in advance for any help! :)
Best regards,
mcc

There's no option to increase the reliability of the system. The options
are all there to match the file system to suit your specific data.
Things like number of files vs average size of files, how many inodes
will you need, block size, what is your reading and writing profile, do
you create and/or delete many files at one time, etc etc

There's not much people on this list can do to help you with this beyond
explaining how options work. I recommend you get out the ext4 man pages
and read them all from beginning to end several times. Then analyse your
own data needs and make a decision.
