I want to ensure that I am correctly applying the concept of the growfs command. I want to remove /dev/ad2s1h and expand /dev/ad2s1g to occupy all of the space left behind by the deletion of /dev/ad2s1h. root@aries:/root# bsdlabel -e /dev/ad2s1 # /dev/ad2s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 524288 0 4.2BSD 2048 16384 32776 b: 4138384 524288 swap c: 586099332 0 unused 0 0 # "raw" part, don't edit d: 524288 4662672 4.2BSD 0 0 0 e: 524288 5186960 4.2BSD 0 0 0 f: 10485760 5711248 4.2BSD 0 0 0 g: 167772160 16197008 4.2BSD 0 0 0 h: 402130164 183969168 4.2BSD 0 0 0 root@aries:/root# df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad2s1a 253678 60858 172526 26% / devfs 1 1 0 100% /dev /dev/ad2s1e 253678 410 232974 0% /tmp /dev/ad2s1f 5077038 4129758 541118 88% /usr /dev/ad2s1d 253678 130346 103038 56% /var /dev/ad2s1g 81245672 67645604 7100416 91% /data /dev/ad2s1h 194736504 99902864 79254720 56% /backup According to http://www.freebsd.org/cgi/man.cgi?query=growfs&sektion=8, it looks like that if I wish to expand /dev/ad2s1g to fill out the slice, the only thing I need to do are the following: -remove /dev/ad2s1h -growfs -s 569902324 /dev/ad2s1g -edit /etc/fstab to remove all references to /dev/ad2s1h Is this correct? Am I missing any other commands? Since the only tool I am familiar with and use for disk partitioning is sysinstall, how do I remove /dev/ad2s1h without resorting to sysinstall? Fdisk? I want to be extremely sure that I am taking the correct steps to perform this operation. Yes, I have backups but this machine is in production and I want to eliminate every possibility of downtime due to issues arising from the improper understanding and use of the 'growfs' command. Thanks. ~Doug
