SUMMARY: Journal File System for Solaris / quick fsck recover

Hi All,

Thanks for the quick responses  -  I appreciate it.

The answer's I received are to look at the Veritas filesystem or to enable
logging on the UFS filesystem.

Here is one of the responses I received:

For Solaris 7 & later, mount with the 'logging' option, e.g. in /etc/vfstab:

/dev/dsk/c1t0d0s0	/dev/rdsk/c1t0d0s0	/mount/point ufs	2
yes	logging

This implements UFS logging, the equivalent of JFS on AIX & removes the need
for fsck on a bad shutdown.

Subject: Journal File System for Solaris / quick fsck recover

Hi All,

I would like to know if Solaris has a Journal Filesystem similar to the AIX
jfs or Linux jfs?

The reason I ask is that I have a server with quite a number of large
filesystems (> 400GB each).
On a few occasions that this server has gone down without a proper shutdown
it has taken up to 11 hrs before the filesystem checks have completed and we
can login again.

I was hoping that implementing jfs will cut this "recovery" time.  If it is
not supported on Solaris, does anyone have any suggestions about other ways
of addressing this?

I will summarise.
