Can't add chunk to dbspace (Grrr!)

ODS 7.22, Unixware 2.1.1, Compaq Proliant 1500 Can someone tell me if I'm doing something wrong? I am adding a chunk to an existing dbspace. I have a 4GB drive I've divided into 1GB slices. I'm trying to add a 1GB slice to a dbspace, but `onspaces` won't let me do it, telling me that the slice is too small for the chunk size indicated. I can only do this if I reduce the chunk size request from 1GB to 600MB. Here's my link to the raw device: lrwxrwxrwx 1 informix informix 20 Aug 14 01:13 allcards_dbs_3_cnk_2 -> /dev/rdsk/c0b0t4d0s1 Here's the VTOC info, showing the slice to be 1024MB in size: (1024 cyls = 1024MB = 1GB) # prtvtoc /dev/rdsk/c0b0t4d0s0 [snip] slice 1: USER permissions: VALID UNMOUNTABLE starting sector: 2048 (cyl 1) length: 2097152 (1024.00 cyls) Here are my attempts at running `onspaces`: $ onspaces -a allcards_dbs_3 -p /home/informix/chunks/allcards_dbs_3_cnk_2 -o 0 -s 1024000Verifying physical disk space, please wait ... The chunk '/home/informix/chunks/allcards_dbs_3_cnk_2' will not fit in the space specified. $ onspaces -a allcards_dbs_3 -p /home/informix/chunks/allcards_dbs_3_cnk_2 -o 0 -s 900000Verifying physical disk space, please wait ... The chunk '/home/informix/chunks/allcards_dbs_3_cnk_2' will not fit in the space specified. $ onspaces -a allcards_dbs_3 -p /home/informix/chunks/allcards_dbs_3_cnk_2 -o 0 -s 800000Verifying physical disk space, please wait ... The chunk '/home/informix/chunks/allcards_dbs_3_cnk_2' will not fit in the space specified. $ onspaces -a allcards_dbs_3 -p /home/informix/chunks/allcards_dbs_3_cnk_2 -o 0 -s 700000Verifying physical disk space, please wait ... The chunk '/home/informix/chunks/allcards_dbs_3_cnk_2' will not fit in the space specified. It finally works when I only request 600MB of the 1GB slice(!): $ onspaces -a allcards_dbs_3 -p /home/informix/chunks/allcards_dbs_3_cnk_2 -o 0 -s 600000Verifying physical disk space, please wait ... Chunk successfully added. Any clues? Am I doing something wrong here???
