RE: HDD Sizes reported wrong?
Thanks Dan I was looking through the handbook and just found it as I got the email :).. Think ill leave it as 8% as speed is important to this server. /Steve -Original Message- From: Dan Nelson [mailto:[EMAIL PROTECTED] Sent: Sunday, 11 July 2004 3:49 PM To: Steven Adams Cc: [EMAIL PROTECTED] Subject: Re: HDD Sizes reported wrong?

HDD Sizes reported wrong?
Hey, I have a LSI MegaRaid Raid card with 5x 36gig raid 5 scsi drives.. This gives me 144gig of useable space. 133 GIG if u do the 1024 bytes calucation. So really its 133gig of useable space all up. Now my /home is getting reported at 108gig(which is right) But for some reason its saying 97gig free and 2.4 gig used.. Im confussed where the other 8.5gig or so is gone?? First I thought it counted the bytes in 1000 not 1024.. But even saying that I should have more space then I have.. /dev/amrd0s1a 2.9G50M 2.6G 2%/ devfs 1.0K 1.0K 0B 100%/dev /dev/amrd0s1h 108G 2.4G97G 2%/home /dev/amrd0s1g 871M34K 801M 0%/tmp /dev/amrd0s1d 4.4G 1.2G 2.8G31%/usr /dev/amrd0s1e 1.9G27M 1.8G 1%/var /dev/amrd0s1f13G 2.1M12G 0%/var/log Thanks Steve ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
