First thanks to all the good people who took the time to answer me. And here are the results and conclusions of the jury: (distilled from answers from at least 6 different sources) 1. No, you do not need Volume Manager to grow an UFS filesystem 2. Yes, you can grow a normal UFS file system by using either: /usr/lib/fs/ufs/mkfs -G -M /current/mount /dev/rdsk/cXtYdZsA newsize or /usr/opt/SUNWmd/sbin/growfs -M /mnt /dev/rdsk/c1t4d0s0 3. The latter command is part of the Volume Manager package. But you do not need a full installation to use the growfs command. 4. Several people gave the good advice to grow busy file systems in small chunks 5. Some people warned that using the command might crash, lockup the system (probably on 'busy filesystems') 6. My personal advise: - go ahead and grow your filesystem online - do not try it without a backup - prefer to do it on a quiet (single-user mode) system. PS: just in case you would be interested, soft partitions of Volume Manager do not take away much of the performance. PPS: the jury is still out on the question why this 'important' feature is unmarketed and even undocumented (the mkfs option -G does not exist according to SUN man pages) Anyhow thanks again, Bart _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagersReceived on Thu Jul 4 12:29:50 2002
