CIS 228 – UNIX System Administration Lab Exercise #7: Setting up an alternate filesystem (/home). Scenario: /home is full you need to allocate a new filesystem to accommodate more user space Review TAR command (Chapter 5) 1) Run grub2-install /dev/sda to reinstall Fedora MBR (See recovery notes). 2) Remove Ubuntu partitions via fdisk 3 3) Review DMESG messages to see devices 4) Display filesystems with du, df –v, mount 5) Add diskquotas for remaining users. How? 6) Add quotaon to system startup . How? 7) Place system into single user or maintenance mode 8) Run fdisk –l to display the hardrive layout 9) Allocate a partition twice the size of current /home allocation (? To view menu). fdisk /dev/sda m n accept default starting cylinder +xxxxM …. Where xxxx is twice the size of the current /home directory p ….. to show results w to write to disk 10) Reboot? 11) Make a new filesystem: mkfs –t ext3 /dev/sdax … x is new partition # Pay attention to messages 12) make a temporary home directory /mnt/hometmp 13) mount the new filesystem under /mnt/hometmp 14) Copy the contents of /home to /mnt/hometmp using commands: cd /home cp –rp * /mnt/hometmp What do the copy command flags do? 15) Change /etc/fstab to mount /home on the new filesystem and /mnt/hometmp on the old file system 16) Reboot 17) Mount old /home partition to /mnt/hometmp 18) Backup /mnt/hometmp directory to /var/tmp using TAR 19) Restore it to /home 20) Backup current /home directory using TAR and GZIP and restore it to /mnt/hometmp Related commands: cp, du, df, fdisk, mkfs, mount, umount, CIS 228 – UNIX System Administration Lab Exercise 8: Using TAR and ZIP, other file systems Make sure you complete LAB 7 1) umount /mnt/hometmp 2) use fdisk /dev/sda to change the old /home partition type from Lab 7 to Fat32 fdisk /dev/sda m t x …. x is old /home partition l …. list partition types b …. set partition type to WIN 95 FAT32 p …. to show results w …. to write to disk 3) Reformat the old /home partition as MSDOS filesystem and call it /share mkfs –t vfat /dev/sdax … x is old /home partition Pay attention to messages 4) Backup /home using TAR and GZIP and restore it to /share.

Filesystem Considerations for Embedded Devices ELC2015 03/25/15
Filesystem considerations for embedded devices ELC2015 03/25/15 Tristan Lelong Senior embedded software engineer Filesystem considerations ABSTRACT The goal of this presentation is to answer a question asked by several customers: which filesystem should you use within your embedded design’s eMMC/SDCard? These storage devices use a standard block interface, compatible with traditional filesystems, but constraints are not those of desktop PC environments. EXT2/3/4, BTRFS, F2FS are the first of many solutions which come to mind, but how do they all compare? Typical queries include performance, longevity, tools availability, support, and power loss robustness. This presentation will not dive into implementation details but will instead summarize provided answers with the help of various figures and meaningful test results. 2 TABLE OF CONTENTS 1. Introduction 2. Block devices 3. Available filesystems 4. Performances 5. Tools 6. Reliability 7. Conclusion Filesystem considerations ABOUT THE AUTHOR • Tristan Lelong • Embedded software engineer @ Adeneo Embedded • French, living in the Pacific northwest • Embedded software, free software, and Linux kernel enthusiast. 4 Introduction Filesystem considerations Introduction INTRODUCTION More and more embedded designs rely on smart memory chips rather than bare NAND or NOR. This presentation will start by describing: • Some context to help understand the differences between NAND and MMC • Some typical requirements found in embedded devices designs • Potential filesystems to use on MMC devices 6 Filesystem considerations Introduction INTRODUCTION Focus will then move to block filesystems. How they are supported, what feature do they advertise. To help understand how they compare, we will present some benchmarks and comparisons regarding: • Tools • Reliability • Performances 7 Block devices Filesystem considerations Block devices MMC, EMMC, SD CARD Vocabulary: • MMC: MultiMediaCard is a memory card unveiled in 1997 by SanDisk and Siemens based on NAND flash memory.

What is ext4 ▐ Ext4 is the successor of ext3 which is developed to solve performance issues and scalability bottleneck on ext3 and also provide backward compatibility with ext3. ▐ Ext4 development began in 2006. Included in stable kernel 2.6.19 as EXPERIMENTAL (ext4dev). Since kernel 2.6.28, ext4 has been released as stable (Renamed from ext4dev to ext4 in kernel 2.6.28). ▐ Maintainers Theodore Ts'o [email protected] , Andreas Dilger [email protected] ▐ ML [email protected] ▐ Ext4 Wiki http://ext4.wiki.kernel.org Page 4 Copyright(C) 2010 NEC Software Tohoku, Ltd.
