Re: good, bad, or ugly?
very good, we are running all zFS filesystems, have been running with zFS filesystems since z/OS 1.6, converted all filesystems except for root under 1.6, and now at 1.8, we made the root a zFS too. no more hfs in our shop. give me zFS anyday - Original Message - From: "Hal Merritt" <[EMAIL PROTECTED]> Newsgroups: bit.listserv.ibm-main To: Sent: Thursday, November 15, 2007 5:08 PM Subject: ZFS: good, bad, or ugly?

I still waiting to hear/experience a positive thing about zFS files... I find the coding of the options confusing and VERY error prone. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Re: good, bad, or ugly?
our zfs filesystems are sms managed, and our cloning procedure had to change very little when switching to zFS - Original Message - From: "Lucymarie Ruth" <[EMAIL PROTECTED]> Newsgroups: bit.listserv.ibm-main To: Sent: Thursday, November 15, 2007 6:48 PM Subject: ZFS: good, bad, or ugly?

Just curious, if one were to be designing a new, state-of-the-art DBMS for example, what would one use for a file medium?
