 Posted: Fri Oct 29, 2021 8:56 am Post subject: NTFS partition does not mount |
 |
|
One of my external hard drives with NTFS partition has stopped mounting, in ubuntu it works ok, what might be the problem in Gentoo? Could you help me please?

NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.

sad_dam,
That looks like a hardware error somewhere in the data link.
HDD failure cannot be ruled out but as it works in ubuntu, that's unlikely.
Which NTFS filesystem driver do you use in both distros?

Not only in ubuntu, in windows it works too. Here he also worked once, but it seems that something went wrong
I have ntfs-3g 2017.3, do you mean this driver? |

sad_dam,
Yes. There is a kernel NTFS driver too.
Gentoo has two versions of sys-fs/ntfs3g. 2017.3.23.5-r1 is stable and 2021.8.22 is in testing.
It way be useful to try the testing version.
The 5.16 kernel, which is not released yet, has a new NTFS driver too.

| Is the Ubuntu install on a different drive in the same system as Gentoo, or is it a separate computer? I wonder if the link between the Gentoo computer and external drives in general is bad, and other systems (Ubuntu, Windows) have good connectors/cables for external drives. |

Everything regarding the NTFS in the kernel, i suppose i included

CONFIG_NTFS_DEBUG=y
CONFIG_NTFS_RW=y |

I have the listed systems each on separate ssd, for checking purpose i simply have been inserting them into my laptop and tried to mount my external hdd, so i am sure there is a problem with the gentoo system since i cant mount only on it. |

sad_dam,
You have both NTFS drivers available. Which one do you use, the kernel or ntfs3g.
They use different filesystem types.
What filesystem type do you use?
You may have both installed ad chose which to use at mount time.
DEBUG options in the kernel are not for users. They are allowed to interfere with normal kernel operation so should be off.
CONFIG_NTFS_RW=y is not safe. It would not do what you think it does anyway.
It used to trash your NTFS filesystem but its been made safer by limiting what it can do to almost nothing.

Didn't know about it, turns out that kernel driver mounts my hard drive, ntfs3g does not
But i would like to fix ntfs3g (since only with it you can mount drives through the user interface?) |

sad_dam,
I'm not well informed on NTFS as I have not used it since 2002.
I don't know what "user interface" you refer to either.
NTFS and other non *NIX filesystems, do not support *NIX filesystem permissions, so *NIX permissions must be faked at mount time.
That's the users problem if you use the kernel NTFS driver. I suspect that ntfs3g does it for you.
There is another major difference. Ever if you set CONFIG_NTFS_RW=y in the kernel, write support is limited to changing the content of an existing file as long as the file size does not change. Its effectively read only.
That will be addressed in the 5.15 kernel. As I write, its 5.15-rc7, so any Monday now.
Which NTFS drive do the other distros use?
If its ntfs3g, which version of ntfs3g is it?

sad_dam,
That's the same filesystem driver on both but it only works on Ubuntu.
That makes my head hurt.
In Ubuntu, with the problem partition mounted, what does show?
Attempt the mount in Gentoo. Post the mount command you used.
Put the Gentoo dmesg onto a pastebin, after the mount fails.

sad_dam,
Ubuntu is using USB Attached SCSI (UAS) which makes all the SATA speedups like DMA, NCQ ash so on available over USB3.
Gentoo is using bulk mode, which is like PIO. Either because the drive is not on a USB3 bus or UAS is not enabled in your Gentoo kernel.
However, both dmesgs show errors like
| Ubuntu: | [ 183.437827] sd 7:0:0:0: [sdb] tag#1 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE cmd_age=2s
[ 183.437896] sd 7:0:0:0: [sdb] tag#1 Sense Key : Hardware Error [current]
[ 183.437922] sd 7:0:0:0: [sdb] tag#1 Add. Sense: Internal target failure |
and
| Gentoo: | [ 296.961939] sd 6:0:0:0: [sdb] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x03 driverbyte=0x00 cmd_age=31s

Both mean you have hardware issues.
for the drive.
Post the output of | Code: | | smartctl -x /dev/... |
You need UAS for that to work as bulk mode usually does not support the low level commands to the drive that are required.
You have a hardware problem. The smartctl output will help to pin down what/where the problem is.

Yes indeed, i included UAS into kernel and now my hdd works, thank you very much for all.

Well, the main problem is solved, but the fact that the hard disk gives some errors not a big problem as it seems to me (or is it wrong?), because it works like normally, unlike his almost deceased brother what cleared his smart and and has speed around of 0.1 MiB/s.

sad_dam,
| Code: | | Model Family: Western Digital Green |
That's the warning sign.
| Code: |
ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE
193 Load_Cycle_Count -O--CK 001 001 000 - 1259880
196 Reallocated_Event_Count -O--CK 200 200 000 - 0
197 Current_Pending_Sector -O--CK 200 200 000 - 12 |
You have exceeded the Load_Cycle_Count for the life of the drive. I knom thatthe limit was a lot less than 1,000,000.
Its normally due to the WDIDLE3 default setting being entirely unsuitable for Linux. This causes excessive head load/unload cycles.
The Current_Pending_Sector count is 12. That is, the drive has 12 sectors that it knows that it cannot read.
The Reallocated_Event_Count is zero, so its not even tried to reallocate those 12 sectors.
That 12 is a minimum. There may be other sectors that the drive cannot read that its not been asked for yet.
The drive can no longer read its own writing. The data in those 12 sectors is probably lost. So its scrap.
How much damage an unreadable sector does depends on the data it contains.
If its file data, that file is lost.
If its a part of a directory, that directory and all the subdirectories are lost.
If it were the root directory ...
When its filesystem metadata damaged, the effect is not predictable.
From the dmesg, we can tell that there is a problem with sectors that the mount command triggers a read of.
The drive is scrap. At best, its a write only drive, like /dev/null.
Do not depend on reading from it for much longer.
Do you need to recover the data, if you can, or do you have validated backups?

No, all important files seem to be ok for me, if something is lost, nothing special, but thanks again, i will take note of the advice and will buy the new hdd (Western Digital Gold 10 tb) |

sad_dam,
Beware Shinged Magnetic Recording (SMR). If you don't know what that is, you probably want Conventional Magnetic Recording (CMR) drives..
