10:53 PM Tom_L: fsck.ext4: The -n and -c options are incompatible.
10:54 PM rue_shop3: ugh
10:54 PM rue_shop3: lets modify it then
10:54 PM rue_shop3: fsck.ext4 -v /dev/sdb1 -c
10:54 PM Tom_L: make no changes and add to bad block list....
10:54 PM rue_shop3: na
10:54 PM Tom_L: run that?
10:54 PM rue_shop3: there are no bad blocks, the smart says so
10:54 PM rue_shop3: verbose and show progess
10:55 PM Tom_L: it's working
10:55 PM Tom_L: probably takes a while ehh?
10:56 PM rue_shop3: yea, is it saying much?
10:56 PM Tom_L: nothing yet
10:56 PM Tom_L: root@wheezy:/home/tom# fsck.ext4 -v /dev/sdb1 -c

10:56 PM Tom_L: Error reading block 37805092 (Attempt to read block from filesystem resulted in short read). Ignore error<y>?
10:56 PM rue_shop3: on another terminal, type dmesg, see if it ends with io or communications errors
10:56 PM Tom_L: ignore error?
10:56 PM rue_shop3: errrrrrrrrrrrrrrrrrrrr
10:56 PM rue_shop3: hold on
10:57 PM rue_shop3: there isn't a backup journal
10:57 PM rue_shop3: hmmm
10:57 PM rue_shop3: say n
10:58 PM rue_shop3: ?
10:58 PM rue_shop3: honestly, the odds are that any files that had pending writes when the failure happened aren't important files
10:58 PM Tom_L: JBD: Failed to read block at offset 23588
10:58 PM Tom_L: fsck.ext4: Input/output error while recovering ext3 journal of /dev/sdb1

10:58 PM Tom_L: /dev/sdb1: ********** WARNING: Filesystem still has errors **********
10:59 PM rue_shop3: did it quit?
10:59 PM Tom_L: yes
10:59 PM rue_shop3: IO error, yea
10:59 PM rue_shop3: let me think
10:59 PM Tom_L: i was installing xilinx
10:59 PM rue_shop3: let me think
10:59 PM Tom_L: and running a lcnc latency test
10:59 PM Tom_L: when it locked up
11:00 PM Tom_L: we can pick this up tomorrow
11:00 PM rue_shop3: do you have 304G of free space on the good drive?
11:00 PM Tom_L: yes
11:00 PM Tom_L: i'm fairly sure
11:00 PM rue_shop3: ok, leave this running...
11:01 PM rue_shop3: cat /dev/sdb1 > /mnt2/image.dd
11:01 PM Tom_L: we can check free space first...
11:01 PM rue_shop3: overnight...
11:01 PM rue_shop3: df
11:01 PM rue_shop3: (drive free)
11:02 PM rue_shop3: -h for human readable
11:02 PM Tom_L: 451g
11:02 PM rue_shop3: ok
11:02 PM rue_shop3: cat /dev/sdb1 > /mnt2/image.dd
11:03 PM Tom_L: available
11:03 PM Tom_L: 425
11:03 PM rue_shop3: I dont know if it'll work, the copy might push thru the errors, it might not
11:03 PM rue_shop3: for fsck to work, we need a readable system, even if there are errors in it
11:04 PM Tom_L: will it copy blank space too or just files?
11:05 PM rue_shop3: its the whole partition
11:05 PM Tom_L: ok
11:05 PM rue_shop3: then we can fix the image and revoer the files **plan a*
11:06 PM Tom_L: i wonder how long it will take
11:06 PM Tom_L: it's going to a ssd
11:07 PM Tom_L: will i get any indication when it's done?
11:13 PM Tom_L: i will shut it down and wait when it finishes
11:16 PM Tom_itx: where will it put the file?
11:16 PM Tom_itx: in root?
11:27 PM rue_shop3: that command would put it in the /mnt2/ folder I had you make
11:28 PM rue_shop3: cat /dev/sdb1 > /mnt2/image.dd
