gptid's in fstab while installing FreeBSD using ISO
Hi All, How do I get gptid's as default in fstab while installing using FreeBSD iso file (Virtual,machine installation) ? Is this possible currently? if not how do I achieve this? I use guided partitioning while installing - If I were to tweak in to the source code which files or drivers I should be focusing on? which drivers write the contents of fstab? PS: any reason why we use device names in the place of gptid's as default in fstab. Thanks, Sainath. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
Re: UUID in fstab.
Thanks John, I have tried as you suggested using a Live CD and yes the partitions uuid's are present in gptid .. I found the UUID's in /dev/gptid - how do I determine which uid corresponds to which partition (ufs or swap or boot) (I used glabel status and after some trial and error I found them) edited the fstab accordingly and everything is working now .. Is there a way to have both the /dev/XXXpYY and /dev/gptid/ present in /dev/ Thanks again for your support.

Re: UUID in fstab.
Thanks for the support. I want to use the uuid's found using sysctl -a in fstab. /dev/gptid/ has only uuid for boot partition.

UUID in fstab.
Hello, How to find UUID's for Disk volumes. I have used sysctl -a | grep uuid and was able to find freebsd-swap b55ff220-dcdd-11e2-a324-00155d55b20c freebsd-ufs b55762fc-dcdd-11e2-a324-00155d55b20c are these the corresponding UUID's for swap and ufs. I din't find /dev/ufsid folder to get the UUID's I have used glabel and was able to create labels, system boots well, everything works fine but I don't want to use labels (operating constraint: to create labels I have to boot into single user mode, is there a way to create labels on mounted partitions (I hope not)). I found gptid folder which has boot UUID can this be used? How to use UUID's in fstab? I have tried using # DeviceMountpointFStype Options Dump Pass# uuid=b55762fc-dcdd-11e2-a324-00155d55b20c / ufs rw 1 1 that din't work. I found (from a post) /dev/ufsid/ should be used in fstab but I don't see ufsid in /dev. Do we need to create this or does the system does it? Note: Using FreeBSD 9.1. created partitions using the guided partition tool. Reason: using a SCSI storage driver which changes the drive name accordingly but freebsd installer (boot) is unable to find the drives which results in boot failure.

Kernel Panic - Unix socket communication in kernel module
Hello, I am writing a kernel module in which I am trying to connect to a UNIX socket (UNIX domain sockets use the file system as their address name space). Kernel module (loadable) acts as a client and User mode program acts as server, I have loaded the module using kldload and communication between user and kernel module works fine, when I try to load the kernel module from loader.conf - auto load the kernel module at boot up leads to kernel panic as the file system is not ready and kern_connect fails. How to notify kernel module that File system is ready? (any specific event flags) Is there any specific location for Unix domain socket files? (currently created it under /root/soc/socket ) Using "MODULE_DEPEND" Can I make the module dependent of file system? Thanks. * * ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
