It seems the bad LBA is not on the checked harddisk. Or (more obvious) I did something wrong... How can I correctly identify the partition, which contains the bad block? How can I get a full list of all bad blocks (if any) from a mounted file systems? How severe is the problem? Thank you very much for any help in advance! Best regards, mcc I ran into this recently on the drive that has my home partition on it. Someone posted that it *may* be fixable without moving data etc etc. I didn't have a backup at the time and nothing large enough to make one so I just ordered a new drive. When I got the new drive in and moved my data over, then I played with the drive a bit. I used dd to erase the drive, then stuck a file system back on it and filled it up. After doing that, the drive seems to have marked that part as bad and doesn't use it anymore. It has passed every test since then. My point is this, backups for sure just in case but you may be able to get the drive to mark that area as bad by moving that data off there. In my case, the files were corrupted and gone. Yea, I might could have sent it somewhere but I ain't into that. To much money for files I can replace if needed. I think it was like 3 or 4 video files. I'd find out what files are there, see what damage has occurred so that you can correct later, then find one really good howto and follow it. From my understanding, if you can move that data in the bad spot off there, the drive sort of fixes itself. If yours works like mine did, you should be OK but I'd use it for stuff that ain't so important. I use mine as a backup drive and test it a lot. ;-) I may trust it again, one day. So, most likely you will have some files corrupted at least. The drive *may* be fixable if you can figure out what files to move so that the drive can do its magic. Key thing is, finding out what to move so that the drive can do its work. Two options, try to move files so the drive can do its thing or move all the data to another drive, do like I did mine with dd and give it a fresh start that way. I didn't feel I had the experience to try and move the files so I took the 2nd option. Now I wish I had done option #1 and took notes that I could pass on. That would likely help you more. BTW, my drive gave that error for weeks and never got worse. I could be lucky on that one so do what needs doing as soon as you can, just in case. The last drive that really failed on me years ago, I got a serious warning from SMART. It even said I had like 24 hours to get my data off. It needs attention in your case but hopefully you will have the results I did in the end and you have time to deal with it. Dale :-) :-) Hi Dale, thank you very much for the explanations you gave...and for the hope in it ;) :) In the meanwhile I found ddrescue... :) It took me five hours to copy the disk (1T) binaryly (this word looks wrong...) to another identical one with ddrescue. This beast is smart...it first copies all what it is able to read

The old way of using mass storage meant the storage had to be unmounted on the phone first, which could break running applications. So I installed mtpfs. It works great for root, but a regular user can't mount the tablet. The mtpfs command immediately returns to the command prompt, with no error message or any other info. I has problems with mtpfs and switched to jmtpfs, which works much better. Or you can install SSHd on the tablet and use scp/sshfs.

Re: [gentoo-user] NFS tutorial for the brain dead sysadmin?
On 26/07/2014 04:47, walt wrote:
In this case, the brain dead sysadmin would be moi :)
For years I've been using NFS to share /usr/portage with all of the
gentoo machines on my LAN.
Problem: occasionally it stops working for no apparent reason.
Example: two days ago I updated two ~amd64 gentoo machines, both of
which have been mounting /usr/portage as NFS3 shares for at least a
year with no problems.
One machine worked normally after the update, the other was unable to
mount /usr/portage because rpc.statd wouldn't start correctly.
After two frustrating days I discovered that I had never enabled the
rpcbind.service on the broken machine. So I enabled rpcbind, which
fixed the breakage.
So, why did the broken machine work normally for more than a year
without rpcbind until two days ago? (I suppose because nfs-utils was
updated to 1.3.0 ?)
The real problem here is that I have no idea how NFS works, and each
new version is more complicated because the devs are solving problems
that I don't understand or even know about.
So, please, what's the best way to learn and understand NFS?
I think you are asking for the impossible :-)
NFS is not easy to set up, and even harder to describe. It is easy to
*use* once it's set up correctly - you just mount something and the only
difference to a local mount is you add an IP address.
NFS uses RPC to do some heavy lifting - I don't know how familiar you
are with this, so here's the quick version:
When you mount something locally, and need to use the mounted
filesystem, kernel calls are used to get at the data. This works easily
as the source disk is local and the kernel can get to it. With NFS, the
source disk is remote and it's the remote kernel that must do the
accessing. RPC is a way to safely ask a remote kernel to do something
and get a result that behaves identical to a local kernel call.
Obviously, this is rather hard to implement correctly.
The original RPC was written by Sun and other newer implementations
exist, like libtirpc - to support useful features like not being stuck
with only UDP. That's what the ti means - Transport Independant.
RPC has been in a state of flux for some time and I too have run into
init-script oddities as things change.
In my case, I have nfs-utils-1.3.0, and rc-update configuredd to start
rpc.statd. This works because
depend() {
...
need portmap
...
}
and in the init.d file for rpcbind:
depend() {
...
provide portmap
}
So rpcbind starts at boot time and all my nfs mounts JustWork
Looks to me like your problem is actually with rpc and more specifically
with what things are currently named today (which could be different to
yesterday). Unfortunately I don't know of a place where this is all
nicely described in a sane manner except inside the init files themselves.

[gentoo-user] Something went wrong with DNS, plz help!
The first reboot after recent update of the system have shown that I cannot open any webpage in Firefox. More exactly, Firefox or my system cannot any more resolve URL to IP address (sorry if I use wrong terms). Thus, host gmail.com gives: ;; connection timed out no servers could be reached Nevertheless dig @8.8.8.8 gmail.com reports the corresponding IP adresses. I have not changed any my network settings and my /etc/conf.d/net file still contains list of my DNS servers that contains server 8.8.8.8 as well but somehow it is not enough any more. :( During my last system update, I suddenly found that I had to update about 150 packages, what was a little bit strange as I update my system at least once a week. I have attributed that to the remnants of gnome2 (now I am using fxce4) that I have not cleaned completely and that is now going to update. So, I deviated a bit from my usual system update routine trying to fix that. Nevertheless, as to my view, during my system update I did nothing to distroy the DNS lookup. Luckily, I save my system update logs and now can attach the last one to this e-mail. Please, help me to recover my internet access, as I still have to do a lot of real work till Monday and have not enough time to investigate this problem alone and without a proper internet access. :( # emerge-webrsync Fetching most recent snapshot ...

Is ECC memory a drop-in replacement for ordinary RAM, or does it need a special motherboard? depends on your motherboard. ASUS boards support ECC officially. You just put it in. With Gigabyte some boards support it, some don't - and they don't advertise it. But on their forums are threads about it. Rest: I have no idea.

It requires both CPU and motherboard support I believe. The RAM itself isn't much more expensive - really just reflecting the cost of the extra capacity required. If you were already going to buy a CPU or motherboard that supports ECC then the incremental cost is almost certainly worth it IMHO. The problem is that if you weren't otherwise going to buy either then the incremental cost to upgrade all the components to support it can add up quite a bit. So, when people say that it is just an extra $10-20 for the RAM, that bay be a rather misleading figure. Rich

Even more strange is that it happened *without* my intervention: just a few reboots (one was no enough!). I'm glad the evil spirits decided to depart. Are you using networkmanager? My resolv.conf says it was created by networkmanager. This, by the way, reminds me MS Windows very much. :)
