2013年5月21日 · This would also work with ext4 volumes: the only difference would be using resize2fs /dev/sdb1 instead of xfs_growfs -d /scratch - and using the correct partition type number for ext4 instead of xfs. The fdisk command can list the type numbers for …

Recently we had a problem where one of the ext4 file-systems seemed unable to handle very large number of files, more than 6mln in this case, in spite of having enough space. Is it 6mln the max number, an ext4 file-system can have when formatted with all the default settings? I tried to Google it but didn't get any definitive answer.

When creating/formatting the ext4 filesystem, make sure to add -O ^extent which means disabling the “extent” feature bit. The following steps will not work if your ext4 filesystem still has “extent” feature enabled. ext2 and ext3 partitions should be fine. Download ext2fsd here. Right-click the downloaded file and click Properties.

2009年5月21日 · The Reiser File System is the default file system in SUSE Linux distributions. Reiser FS was designed to remove the scalability and performance limitations that exist in EXT2 and EXT3 file systems. It scales and performs extremely well on Linux, outscaling EXT3 with htrees. In addition, Reiser was designed to very efficiently use disk space.

2022年1月1日 · You need to comment on this disk on /etc/fsb and reboot your system to solve this, after formatting you have to change the disk type on /etc/fsb from ext4 to xfs and reboot your system. like this : /dev/sdX1 /mount/point xfs defaults 0 1 Restore your backup

2011年6月20日 · I don't know if it applies to you, but just in case: most of the time the huge majority of the apparent overhead of ext2/3/4 will be due to the default significant amount of reserved blocks for root. Make sure you specify -m 0 (or 1) to mkfs.ext4 when creating the filesystem or to tune2fs if adjusting it afterwards. The default is 5, which ...

but to go from something like jfs to ext4 seems highly improbable, without first copying your /home files to another partition or external hard disk. even then, you would want to create a new user on your system, with a home directory somewhere like /tmp/tempuser or copy your configurations for your user, usually the 'dot' files (files ...

2015年1月22日 · Ext4 Ext4 is another filesystem that has support for SSD. It is considered as stable since 2.6.28 and is mature enough for daily use. Contrary to Btrfs, ext4 does not automatically detect the disk nature; users must explicitly enable the TRIM command support using the discard mount option in fstab (or with tune2fs -o discard /dev/sdaX).

2024年2月9日 · Afterwards, I rebooted back into the system and it functioned normally; however, 10 minutes later after returning to the machine having stepped away, it had failed again (the shortest uptime yet endured). The console was filled with these errors: __ext4_find_entry:1682: inode #2 (<process name>): reading lblock 0

Ext4 has a theoretical limit of 4 billion files, which is restricted by the size of inode number it uses to identify each file (ext4 uses 32-bit inode numbers). However, as John says, ext4 allocates inode tables statically, so the actual limit is set when the filesystem is created. The df command shows you a count of free inodes on your filesystem:
