inodes, so you need to disable a flag with XFS for "inode64" which means on files over 2GB XFS' will need to create multiple inodes instead of 1 at the beginning of the file which hurts it's performance. Some history about XFS was ported from SGI's IRIX in the early 200X's, with...

In an earlier blog post, I wrote about how we can configure an Azure Linux (Ubuntu) VM with a RAID 0 array of data disks and mount XFS on the array. The goal of doing this was gaining disk I/O, hence performance.In order to substantiate this claim, I ...
Btrfs would probably fit most of my needs, but it's very slow in Phoronix benchmarks. XFS has impressive performance, but I've heard it can cause data loss. Thanks for your advice. zfs network-attached-storage ext4 xfs btrfs Share Improve this question Follow asked Jan 28, 2020 at 14...
背景前期一直处理xfs,lvm磁盘的扩容很少处理ext4的磁盘扩容今天发现自己竟然对这一块有盲区。 晚上回家自己学习研究了会儿, 发现知识点还挺多 所以总结一下。问题虚拟一开始设置的数据盘时100GB大小 但是发下使用一段时间之后已经不够用了。 所以要扩容到200G 虚拟机控制台的处理很简单, 直接进行一下 resize就可以...
SPDK(Storage Performance Development Kit)是一个用于构建高性能存储应用程序的开源软件开发工具包。它专注于利用现代硬件和存储技术的特性,以最大化存储应用程序的性能。 SPDK 提供了一组库、驱动程序和工具,帮助开发人员构建低延迟、高吞吐量的存储应用程序。

然而,某些Linux开发者因稳定性原因而拒绝将这些延伸包应用在ext3上[2],并要求其作为ext3的分支,改名为ext4并另行开发,以免影响到目前的ext3用户。...目前大多数文件系统做到这点的方式是直接产生一个填满0的文件;ext4和XFS可以使用Linux核心中的一个新的系统调用“fallocate()”取得足够的预留空间。...为了避免...

By now, you have reviewed the read and write performance on both the XFS and EXT4 filesystem using two different FIO engines – psync and libpmem. Given that, thanks to DAX, the libpmem engine bypasses the filesystem during data access, performance with libpmem is consistent ...
