Re: [zfs-discuss] bootfs ID on zfs root

2011-05-12 Thread Jim Klimov
Sorry, I guess I'm running out of reasonable ideas then. One that you can try (or already did) is installing Solaris not by JumpStart or WANBoot but from original media (DVD or Network Install) to see if the problem pertains. Maybe your flash image lacks some controller drivers, etc? (I am not

Well, the Sun-supported way is separating /var from the common root. In our systems we do a more fine-tuned hierarchy of separated /usr /opt /var in each BE and sub-separated /var/adm /var/log /var/cores /var/crash and /var/mail shared between boot environments. This requires quite many tricks

Ah, yes, regarding the backdoor to root fs: if you select to have some not-quoata'ed space hogs in the same pool as your root FS, you can look into setting a reservation (and/or refreservation) for the root FS datasets. For example, if your OS installation uses 4Gb and you don't think it would

The thing is- as far as I know the OS doesn't ask the disk to find a place to fit the data. Instead the OS tracks what space on the disk is free and then tells the disk where to write the data. Yes and no, I did not formulate my idea clearly enough, sorry for confusion ;) Yes - The disks

Thank you for your insight. This is a system that was handed down to me when another sysadmin went to greener pastures. There were no quotas set on the system. I used zfs destroy to free up some space and did put a quota on it. I still have 0 freespace available. I think this is due to the

Thanks everyone. Your inputs helped me a lot. The 'rpool/ROOT' mountpoint is set to 'legacy' as I don't see any reason to mount it. But I am not certain if that can cause any issue in the future, or that's a right thing to do. Any suggestions ? Thanks Arjun

This is a slow operation which can only be done about 180-250 times per second for very random I/Os (may be more with HDD/Controller caching, queuing and faster spindles). I'm afraid that seeking to very dispersed metadata blocks, such as traversing the tree during a scrub on a fragmented
