I am about to attach 24 1 TB drives to a 3ware 9650SE-24 raid card and attach it to a FreeBSD 6.3-RELEASE system.
I am going to newfs that raw disk and turn it into one giant 24 TB UFS2 filesystem:
newfs -i 65536 -U /dev/da1
I intend to enable quotas on this system BUT I do not intend to set any >2TB quotas for any one particular user.
Questions:
- anything else I should know ? Any danger ? Other than decreasing inode density, like I am with '-i 65535' are there any other settings I should be considering ? I will set kern.maxdsiz="2572000000" ... which I hope will be enough for fsck.
- I have been (sort of) following the recent thread about >2TB quotas - let's say I have a user with _no quota set_ but they amass more than 2 TB of files - is that still a problem ? Or is it only a problem if I actually set a quota for them of >2TB ? Will repquota report correctly, even though they don't have a quota set ?
Thanks.
