free space problem

free space problem

[Huszár Viktor Dénes]

Hi all,

 

we encountered a problem with XFS free space and perhaps reserved space. It
reports to have 82 gb free on the raid, however its not possible to write on
the file system. Please tell me if you need more details, we have read
through the previous free space threads, but found nothing useful. We run
2.6.23 kernel.

 

Thanks in advance,

 

Vic

Look in /var/log/messages and the output of dmesg command for xfs
related messages and post them here, please.

There is nothing extraordinary in it, you can see umount-mount and that it
was mounted after all xfs activity (check, repair, db).

What is the error you are getting? Does 'dd if=/dev/zero of=/mntpt/file bs=512
count=1' work? If not, what's the error?  What's the output of 'df -h' and
'df -ih'? Output of 'xfs_info <mntpt>'?

Cheers,

Dave.

No, unfortunately not. There are not many small files and the inode usage is
1%. See.

Actually, from yesterday it started working again. So the xfs_info of
yesterday I can't send when it was not working. When it was not working, in
dd there is nothing extra. A simple no space left on device. And kernel does
not log anything (dmesg). The problem appeared suddenly and mysteriously,
and it disappeared in the same way... If it happens again, I'll send you the
info immediately. 

The problem was there for couple of days, we umounted and ran xfs_repair
several times, and we mounted it back and not even mkdir worked, or in 5-10
minutes we wrote few Gb space on the disk and still plenty of Gbs were free,
but it said: no space left on device. So if it appears again, I'll get back
to you guys. 

Im really thankful for your help!

Yes, but if you have fragemented free space then it is possible that there
are not enough free extents large enough (or aligned correctly) to
allocate more inodes. The number of "free inodes" reported doesn't take
this into account; it only looks at the number of free blocks and converts
that to a theoretical number of inodes that could be allocated in that
space (i.e. it assumes perfect fit and no waste). 

In this "not quite full filesystem" situation, you can write data to the
filesystem, but any attempt to create a new inode (new file, directory,
etc) will fail with ENOSPC. This sounds like the symptoms you are
reporting....

Cheers,

Dave.

What you described might happen with lot of small files, but in our case,
our attempts fail to create a new inode and fail to write data. You suppose
that we have fractured free spaces, and on these fractures no inodes can be
created. In our case, the situation was different, however as it started to
work again I still can't provide you any xfs_info/debug.

Thanks again,
Viktor

Yes, but if you have fragemented free space then it is possible that there
are not enough free extents large enough (or aligned correctly) to
allocate more inodes. The number of "free inodes" reported doesn't take
this into account; it only looks at the number of free blocks and converts
that to a theoretical number of inodes that could be allocated in that
space (i.e. it assumes perfect fit and no waste). 

In this "not quite full filesystem" situation, you can write data to the
filesystem, but any attempt to create a new inode (new file, directory,
etc) will fail with ENOSPC. This sounds like the symptoms you are
reporting....

Cheers,

Dave.

Peter, are you Hungarian :) too?
For us this 0.3 % is vital 50-100 GBytes. Do you think that if we would have
a free space arund 400-500 Gb the problem would never appear?

Thanks, Viktor

So you effectively have a full filesystem. Inode allocation
may be impossible as the filesystem approaches full as there
is not enough contiguous free space to allocate them in.

Also, you are probably using the inode32 allocator (i.e. no inode64
mount option), which means inodes can only be placed in the first
1TB of the filesystem, and that means those AGs are probably out of
space.

Given that you have 523GB AGs, that means inode will probably only be
put in AG 0, ad that's probably out of space. What does:

# xfs_db -r -c 'freesp -s -a 0' /dev/mapper/a-a

give you?

FWIW, This problem will come and go as you unlink files and change
the pattern of freespace...

Cheers,

Dave.

RE: free space problem

[Huszár Viktor Dénes]

Okay guys, we figured out what is the real problem with the xfs, I just need
your help now.

Currently our server has an 880448 number as icount, which we figured out
like this:

xfs_db -r -c sb -c p /dev/a/a | egrep icount\|ifree
icount = 880448
ifree = 0

although df -i sates this:

df -i
Filesystem            Inodes   IUsed   IFree IUse% Mounted on
/dev/md0                5.3M    301K    5.0M    6% /
tmpfs                   2.0M       5    2.0M    1% /lib/init/rw
udev                    2.0M     475    2.0M    1% /dev
tmpfs                   2.0M       1    2.0M    1% /dev/shm
/dev/mapper/a-a          60M    860K     59M    2% /var/www/users

If we delete a file ifree is going to be 1. if we delete 200 files, ifree
becomes 200 so there is an obvious relationship here. If ifree is 0, we can
not upload anymore.

So the question is: how can we increase the icount without formatting the
partition?

Please help!! Thank you in advance,

Viktor

Then maybe you simply ran out of inodes. It's common if you have lots
of small files. There is a way to increase the number of inodes but I
don't remember it right now.

Is it mounted with the inode64 option?

You should try it then. You must unmount it and remount it for this to
take effect. Either add "inode64" to the option line in /etc/fstab, or
use mount -t xfs -o inode64 /some/device /some/mountpoint

YES! Finally the problem is solved! Thank you Emmanuel and everyone else!
After adding inode64 to the mount option [only umount and mount worked, with
remount it didn't] it works. Although the icount and ifree numbers have not
changed, we can write to the disk. 

Hope this will help anyone who encounters this problem. In the xfs man and
debian docs we could not find anything about this inode64, so thank you once
again for the help!!!!

I had this same problem 2 weeks ago, that's why I remember clearly what
to do :)

I can think of two places off the top of my head where it is
documented:

Documentation/filesystems/xfs.txt in your local kernel source tree:

  inode64
        Indicates that XFS is allowed to create inodes at any location
        in the filesystem, including those which will result in inode
        numbers occupying more than 32 bits of significance.  This is
        provided for backwards compatibility, but causes problems for
        backup applications that cannot handle large inode numbers.

$ man 8 mount

  inode64

	Indicates that XFS is allowed to create inodes at any location in the
	filesystem,  including  those which will result in inode numbers occupying more
	than 32 bits of significance.  This is provided for backwards compatibility,
	but causes problems for backup applications that cannot handle large inode
	numbers.

RE: free space problem

[Huszár Viktor Dénes]

Thank you, now I found it as well. I cant believe I missed this! Emmanuel :)
we solved the problem temporarily by increasing the free space to 100 GB,
however, we had no idea it has anything to do with the number of icount or
ifree.

Dave, thanks as well.
