thanks for your reply. you know i have a sensitive server and unfortunately it is located some where that power outage happens much. so i want guarantee my data and avoid data lost and file corruption in my server. i do not have any problem in RAM and hardware. i don't know which approach is more suitable for my server. using soft-update or ZFS. please help me to select the best one. thank you so much On Thu, May 23, 2013 at 4:28 PM, Warren Block <wblock@wonkity.com> wrote: > On Thu, 23 May 2013, saeedeh motlagh wrote: > > hello every body >> >> i have a question about fixing file corruption in freebsd. >> >> now i have freebsd8.2 and some times file corruption happened on it. this >> issue has a heavy cost for me and i want to avoid it or fixit it >> completely. so my question is: >> >> is it better to upgrade my freebsd to 9.1 and use soft update or migrate >> from UFS to ZFS? >> > > That's a judgement call, which means "it depends". > > > i heard so much about soft update -that is added in freebsd9.1- which can >> fix file corruption in acceptable way with low cost but i don't know how >> much is reliable and efficient. >> > > Several things: > > Soft updates have been around for quite a while. > Soft updates journaling is the new addition. > Neither of these address file corruption.
