Re: Problems with gjournal or something else.

Then did:

newfs -J -b 8192 -f 1024 -g 50000 -h 20 -i 40960 /dev/twed1s1f

gjournal load
gjournal label -f /dev/twed1s1f
tunefs -J enable -n disable /dev/twed1s1f
mount -o noatime /dev/twed1s1f.journal /NEW/suit

It's wrong order. See gjournal(8) manual page, EXAMPLES section. You
cannot create file system and then put journal on the same partition.
gjournal would warn you about that, but you used force (-f) option.

Here is what man says:

Configure gjournaling on an existing file system, but only if gjournal
allows this (i.e.: if the last sector is not already used by the file
system):

umount /dev/da0s1d
gjournal label da0s1d da0s1e
tunefs -J enable -n disable mount -o async /dev/da0s1d.journal /mnt
mount /dev/da0s1d /mnt

However, this simple does not work.
gjournal label da0s1d da0s1e - WILL FAIL ON EXISTING FS!
Need to use -f switch for this.

So, those whole thing will look like this

1: newfs /dev/da0s1d here we have our EXISTING filesyetm
2: gjournal load
3: gjournal label -f /dev/da0s1d 4: tunefs -J enable -n disable /dev/da0s1d
5: mount -o async /dev/da0s1d.journal /mnt

Now, when you start to fill /mnt you will get error=5 with offset out of range
of the filesystem, beceause metadata for the filesystem is used from
/dev/da0s1f (step1) but gjournal used 1GB for the journal.

This error goes away if i add additional step between 4 and 5
4.5: newfs /dev/da0s1d.journal

question1:

4: tunefs -J enable -n disable /dev/da0s1d
really must be for /dev/da0s1d or for /dev/da0s1d.journal

question2:
man says
gjournal label da0s1d da0s1e && tunefs -J enable -n disable && mount -o async /dev/da0s1d.journal /mnt || mount /dev/da0s1d /mnt

why there is no fs argument in tunefs? mistake?
what does
'mount -o async /dev/da0s1d.journal /mnt || mount /dev/da0s1d /mnt;
mean? (note ||)

A couple more questions:
1) What size of journal to pick?
2) How stable is the whole thing?
