For running todays tests, Ubuntu 10.10 was used with its Linux 2.6.35 server kernel as to use KQ Infotech's official ZFS Linux packages. The ZFS Linux performance was then compared to that of EXT4, Btrfs, and XFS using the Linux 2.6.37 kernel to represent the latest stable look at those file-systems' performance.
File-system benchmarks have become quite common to Phoronix in the age of EXT4 and Btrfs with these new file-systems driving much of the interest and as we have also been finding the Linux file-system performance to change between kernel releases (and in some cases, the performance has changed a gr...
How To Convert An ext3/ext4 Root File System To btrfs On Ubuntu 12.10
ext3 and ext4 file systems can be converted to btrfs. For non-root
file systems, this can be done online (i.e., without reboot), while for
root file systems we need to boot into some kind of rescue system or
Live CD.
I have seen that Ubuntu 11.10 is offering Ext4 as default file system. As I have googled some time on ext4 and found that ext3 is quite stable that ext4 as it still has some bugs.
Even the Ubuntu Documentation is referring Ext3. Link
So, I would like to know whether Ext4 is currently stable on 11.10 or not than Ext3
Does anyone know if Solaris 11 (Sparc version) supports mounting ext3/ext4 or even better Btrfs volumes ?
Most of the topics I find on the web are quite outdated (2006/2007) and reference old versions of Solaris which were pretty unfriendly to Linux oriented FS.
I was hoping that the situation changed, so if you have any info or pointers, I'd really appreciate.
Thanks per advance,
I was wondering if ext4 is stable enough for production use? I have read through most of the ext4 reviews but they are a little dated, most of them referring to ubuntu 9.04 and the 2.6.28 kernel. Any thoughts?
Thanks,
iz
Basic comparison between ext4 vs ext3 vs NTFS, it will show the benefits of using ext4 file system, all of them supporting journaling file system will talk more about journaling.
Published at LXer:
The most common Linux file-systems we talk about at Phoronix are of course Btrfs and EXT4 while the ZFS file-system, which is available on Linux as a FUSE (user-space) module or via a recent kernel module port, gets mentioned a fair amount too.
What is going on with the file system "btrfs" is it worth looking into yet will there be any speed improvements? I understand Ubuntu is using it now? Is that just in 12.10 or 12.04, I haven't looked, (not really sure how to.)
(mod please take off "not ext4" from my subject, I changed what I wrote and forgot to change the title Thank you Rob)
