 |

gentoo is set up completely and working. then i hot a second hd, put it into my box, and now after same time i found out, that on boot my root-partition is checked after sometime or a number of reboots, but not the second hd, that i got.
where do i have to tell him, that also this hd should be checked from time to time?

you can change the number of mount needed for a check with tune2fs (use -j if it's journalised fs, ext3)

This is done in /etc/fstab on a per filesystem basis. | man fstab wrote: | The sixth field, (fs_passno), is used by the fsck(8) program to determine the order in which
filesystem checks are done at reboot time. The root filesystem should be specified with a
fs_passno of 1, and other filesystems should have a fs_passno of 2. Filesystems within a drive
will be checked sequentially, but filesystems on different drives will be checked at the same
time to utilize parallelism available in the hardware. If the sixth field is not present or
zero, a value of zero is returned and fsck will assume that the filesystem does not need to be
checked. |
So, where your / fs entry may look like | Code: | | /dev/hda4 / ext3 noatime 0 1 |
You might have something like this for your fs on the 2nd HD | Code: | | /dev/hdb1 /some/path ext3 noatime 0 2 |

|

Hello again,
what is the "gentoo-way" of filesystem checks? And how do i have to tweak it? I didn't find any docu by now concerning this VERY important feature. Is there one?
Kind regards, Qeldroma |

Can you be more specific with your question?
Filesystems are automatically checked at boot if needed (which is seldom if you are using journaling filesystems and have a stable machine), except when this is turned off in /etc/fstab.
If you want to do regularly scheduled checks anyway, see the man pages on the fsck programs on how to check filesystems when they are mounted.
To repair errors, they have to be unmounted, so you could do that either from a livecd system, or by booting with init=/bin/bash or /bin/busybox and check from there.
HTH.

man fstab should tell you what you want to know.
| Code: | The sixth field, (fs_passno), is used by the fsck(8) program to deter-
mine the order in which filesystem checks are done at reboot time. The
root filesystem should be specified with a fs_passno of 1, and other
filesystems should have a fs_passno of 2. Filesystems within a drive
will be checked sequentially, but filesystems on different drives will
be checked at the same time to utilize parallelism available in the
hardware. If the sixth field is not present or zero, a value of zero
is returned and fsck will assume that the filesystem does not need to
be checked.

@nixnut: Thx! Didn't knew there is a fstab-variable 
@all: I've got a server running journalled, but it looses files?! Don't know how to recover, so i wanted to be sure, that gentoo in standard-installation DOES fixups on boot....
What i really wonder is, that this server has got SCSI-RAID10 and is nevertheless loosing data?!?!?!?
It's an IBM z205, afaik...
I just want to get my neck out of the rope on this fault...

|
|
I keep getting this message at boot right before the system tries to mount the root xfs filesystem as read/write.
What does that mean? I can not get my system to boot up because of no read / write - it ask for root password for maintenace but xfs_check and xfs_repair do nothing... same thing every time I boot up.

| Code: | # <fs> <mountpoint> <type> <opts> <dump/pass>
LABEL=Root / ext3 noatime,data=journal 0 1 |
This is an excerpt from my /etc/fstab file. Yours most likely has a zero in the last column of the line that defines your root filesystem. Change it to a one so that it is checked on the first pass of the fsck. A zero value tells fsck to not check a filesystem, which is not a good thing for your root filesystem.  |

I have tried that but I still get the same error:Skipping root filesystem check (fstab's passno == 0)Remounting root filesystem read/write ...Root filesysten coud not be mounted read/write ;{Give root password for maintenance(or type Contro - D continue):I've tried xfs_repair in knoppix (and that's after a xfs_check)I've tried doing an xfsdump of the fifesystem, repartitioning the /dev/hda2 partition and then doing a xfsrestore... still no luck.I have no idea what is causing this error... flat out!

| Post the contents of your /etc/fstab file as well as the output of running "fdisk -l". |
