Hi, Ive ben searching on de list archives related to the following: On wiki http://www.gluster.org/docs/index.php/Guide_to_Optimizing_GlusterFS#Tuning_Kernel_Parameters You can read... " Ext3 also has directory indexing which is very much useful for the directories which have larger files or many files by boosting the file access. This is done by generating hashed binary trees to store directory information. But by default if a directory grows beyond a single disk block its automatically indexed using a hash tree. To enable directory indexing use the following commands $ tune2fs -0 /dev/hda1 " But the man page for tune2fs says: " -O [^]feature[,...] Set or clear the indicated filesystem features (options) in the filesystem. More than one filesystem feature can be cleared or set by separating features with commas. Filesystem features prefixed with a caret character ('^') will be cleared in the filesystem's superblock; filesystem features without a prefix character or prefixed with a plus character ('+') will be added to the filesystem. The following filesystem features can be set or cleared using tune2fs: dir_index Use hashed b-trees to speed up lookups in large directories. " this would lead to .. $ tune2fs -O dir_index /dev/hda1 My distribution is OpenSuse 10.3 ¿is this an error on he wiki or there are more ways to activate dir_index flag in other distributions.?
