I have had further problems with this RAID. Today I was extracting files fr= om a 2Gig zipped tar andthe node ad4 failed. I could not not figure out wha= t to do after that. I triedgmirror forget datgmirror insert dat ad4 that ga= ve me an error ad6 device not found So I tried a reboot. That was even wors= e. as when the mirror came up ad4 was restored only!in a degraded state. Th= en I recieved a endless stream ofg_vfs_done READ errors! I had to turn the = machine off. So I decided to destroy the mirror. I amended fstab to not mou= nt the mirror and mounted ad4 into /homewhere the mirror usually resides an= d back everything up.I did :gmirror stop datwhich worked until GEOM timed o= ut and started it again.I quickly didgmirror stop datgmirror unloadmount /d= ev/ad4 /home Then I rebuilt the mirror:gmirror label -b split -s 2048 dat a= d4 ad6gmirror loadnewfs /dev/mirror/dat -Umount /dev/mirror/dat /home2 and = copied all the files back- well tried to. The mirror broke again.I had to d= o all the work again. Except this time I left off SOFT-UPDATES.I copied all= the files again and this time the mirror survived. Am I doing something wr= ong when I build the mirror? Or is therean issue with SOFT-UPDATES? my syst= em again isCeleron 800Mhz, 768MBad2 - 11Gig HD IDEad4,ad6 - WD 320Gig SATA= SiL3512 PCI SATA controller Thanks,Salik.> From: chameeyass@hotmail.com> To= : freebsd-geom@freebsd.org> Date: Mon, 2 Jun 2008 21:18:51 +0000> Subject: = mirror device detached on large file copy> > > Hello running FreeBDs 7.0 on= a Celeron 800Mhz and I copied a 1.8G file across from my Windows box to th= e FreeBSD box.
