[opensuse-factory] Require feedback on assigning block size for partitions for new drive
Hello List Mates, I have noticed that when formatting partitions I click on the Option button under EXT4. The block size is set to auto to let the filesystem select the block size according to size etc. When all is done, I boot my SystemRescue CD and run TestDisk. It informs me about a problem with the superblock. My question to you is.. Can I assign 4096 bytes rather than use auto? -- Cheers!

Follow Up TestDisk showed this: superblock 0, blocksize=4096 [] superblock 32768, blocksize=4096 [] superblock 98304, blocksize=4096 [] superblock 163840, blocksize=4096 [] superblock 229376, blocksize=4096 [] superblock 294912, blocksize=4096 [] superblock 819200, blocksize=4096 [] superblock 884736, blocksize=4096 [] superblock 1605632, blocksize=4096 [] superblock 2654208, blocksize=4096 [] To repair the filesystem using alternate superblock, run fsck.ext4 -p -b superblock -B blocksize device Roman -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

For the partitioning? Yesterday I checked my root partition with: tune2fs -l $(df / | gawk 'FNR==2 {print $1}' ) Results: tune2fs 1.42.8 (20-Jun-2013) Filesystem volume name: / Last mounted on: /root Filesystem UUID: 75d5f043-0c79-403e-a1f8-a4e6fdda6a25 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize Filesystem flags: signed_directory_hash Default mount options: user_xattr acl Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 6594560 Block count: 26351360 Reserved block count: 263513 Free blocks: 23659139 Free inodes: 6270606 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 1017 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 8192 Inode blocks per group: 512 Flex block group size: 16 Filesystem created: Sat Jul 5 12:45:33 2014 Last mount time: Wed Jul 9 07:49:16 2014 Last write time: Wed Jul 9 07:49:16 2014 Mount count: 5 Maximum mount count: -1 Last checked: Mon Jul 7 08:13:51 2014 Check interval: 0 (<none>) Lifetime writes: 27 GB Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 First orphan inode: 2490595 Default directory hash: half_md4 Directory Hash Seed: fd5f14b3-e299-4cf6-b318-42e6ecbf9b3a Journal backup: inode blocks It looks good to me.

BTW: Time to revisit 'info df': there's no need for awk(1)ward field parsing of df's output anymore. Since coreutils-8.21, df supports the --output option by which you can directly select which column you want to print. (You still have to get rid of the header line, here using "sed 1q"): tune2fs -l $(df --output=source / | sed 1d) Have a nice day, Berny -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Have a nice day, Berny Good one! It's so much simpler ;-)
