[gentoo-user] Ext3 FS File Size Limits
I've been going around with this little problem for a while. I have several 30GB files I'm trying to restore from an NTFS formatted external backup to an ext3 partition, yet every attempt has failed right after 16GB of copying without fail or error message. They silently failing and I'm stumped. One of the possible causes I've thought of was running out of innodes but don't know how to check that or any of the other options used to create the file system on - anyone want to help there? I've also decided to look at the mke2f.conf file in /etc and see some default options being passed that may be causing the problems [defaults] base_features = sparse_super,filetype,resize_inode,dir_index,ext_attr default_mntopts = acl,user_xattr enable_periodic_fsck = 0 blocksize = 4096 inode_size = 256 inode_ratio = 16384 Normally I use either a 1024 for most everything due to the many small files though for the partition I'm attempting to restore the files to, I've used 2048 as a compromise due to the number of larger files (music/videos) and critical backups from /etc I've also tried it with a default 4096 size on a 32GB ext2 formatted flash drive but even then, it's failing at 16GB w/o any error message.

You can try `touch`ing a file on that partition and see if it fails. If so, you've run out of inodes; no need to peek at fs internals :)

What command are you using to copy this data? Try: rsync -av /source/ /destination/ and see if you get any output when it fails. There have been other guesses, but with the information you've provided, that's all we can do. My guess is you're using cp and it gets to a large, corrupt file and fails. Post back with your command and it's output, then the rsync command above and it's output; as well as the inode command Dale gave you, and any other applicable commands you've had suggested. -- Happy Penguin Computers ') 126 Fenco Drive ( \ Tupelo, MS 38801 ^^ supp...@happypenguincomputers.com 662-269-2706 662-205-6424 http://happypenguincomputers.com/ A: Because it messes up the order in which people normally read text.

Ext* started as a UFS clone and UFS filesize is limited to 2**63 while UFS filesystem size is limited to 1 TB. Just for ease of comparison, 16GB = 2**34 bytes = 2**24 1k blocks. 1TB = 2**40 bytes.

When the blocksize doubles, a single indirect block points to twice as many direct blocks, each of which is double the size. For double indirect you get twice as many single indirect, etc. There are plenty of places to read about this.

I would have expected the maximum file size to be a AM number of blocks, which makes it seem strange that doubling the block AM size multiplies max file size by 16. Doubling the block size means that the structure specifying which blocks are in use by a given inode is twice as long. And the structure supports indirect blocks, which contain references to the actual blocks used by the file data. So you get one doubling for the size of the blocks, and another three for the number of blocks each file can use. Most ext3 and ext4 filesystems use 4096 octet blocks. -JimC -- James Cloos cl...@jhcloos.com OpenPGP: 1024D/ED7DAEA6
[gentoo-user] Poor sound quality
Hello, My sound started sounding like crap ~6 months ago. Imagine someone has control of my volume knob and is quickly (~5Hz) turning the volume knob up and down. That is a rough idea of what it sounds like. This happens whether I am listening a beautiful song or whether I'm listening to 'white noise'. Happens with my laptop speakers or with headphones. Can anyone hazard a guess as to what is wrong? FYI I'm using a Dell M6600 with the same amd64 gentoo install for ~2 years. Thank you, Chris
