Problem starting stone "reason = File is on NFS, $GEMSTONE_DATADIR/extent0.dbf"

Hi  Mariano

I think this is related to the message James sent out on 4th October?

According to Apple, "When you install macOS High Sierra on the Mac volume of a solid-state drive (SSD) or other all-flash storage device, that volume is automatically converted to APFS." --https://support.apple.com/en-gb/HT208018
Note that this is not a problem for non-SSD drives, so the problem is not as wide-spread as I first thought. Also, as a workaround, you can set the following in the stone config file:

  STN_ALLOW_NFS_EXTENTS=TRUE;

Watch the release notes for an eventual fix.

If you need to run GemStone on a Mac, I’d suggest you wait till this is resolved before upgrading. Stay tuned for more information...

Hi guys,

It's a while since I do not try to start local stones in my OSX box. I am trying to start a 3.3.3 stone now and I am getting this error (I am using latest GsDevKit_home):

--- 12/14/17 09:35:55 -03 ---

    GemStone is unable to open the file $GEMSTONE_DATADIR/extent0.dbf

       reason = File is on NFS, $GEMSTONE_DATADIR/extent0.dbf

    An error occurred opening the repository for exclusive access.

    Stone startup has failed.

Checking the extent, I cannot see anything obviosuly wrong:

❯ ls -la $GEMSTONE_DATADIR/extent0.dbf                                                                                                                                    -rw-r--r-- 1 mariano staff 150994944 Feb  2  2017 /opt/gemstoneAdditions/GsDevKit_home/server/stones/quuveTesting333/extents/extent0.dbf

And of course, this is not a NFS file system:

 ❯ sudo mount                                                                                                                                                              

/dev/disk1s1 on / (apfs, local, journaled)

devfs on /dev (devfs, local, nobrowse)

/dev/disk1s4 on /private/var/vm (apfs, local, noexec, journaled, noatime, nobrowse)

map -hosts on /net (autofs, nosuid, automounted, nobrowse)

map auto_home on /home (autofs, automounted, nobrowse)

/dev/disk2s2 on /Volumes/Seagate Backup Plus Drive (hfs, local, nodev, nosuid, journaled)

com.apple.TimeMachine.2017-12-14-092610@/dev/disk1s1 on /Volumes/com.apple.TimeMachine.localsnapshots/Backups.backupdb/MacBook Pro/2017-12-14-092610/Macintosh HD (apfs, local, read-only, journaled, nobrowse)

I checked my emails and googled it but I found nothing.
